The important bit here is that animals generally live half as long in the wild than in captivity. If they get weakened from illness injury or age those pathogens, parasites will absolutely kill wild animals.
@@deinsilverdrac8695 sea animals are not really relevant here. Elephants, apes, lions etc live longer in captivity. Especially if you compare average lifespan and not the lifespan of the exceptions. That is true even if you discount predation of the young.
@@deinsilverdrac8695 lol wrong, there's literally scientific studies and observations that captive raised animals live longer and are healthier then their relatives in the wild, dying from predators, diseases, parasites, pollution, poaching, and not enough food, there's a lot of reasons why wild animals love shorter lives lol
@@adam-k apes and elephant barely live longe rin captivity, and yes, marine animal are still relevant here. And actually a lot of species can't be kept in captivity because they die quickly out of their natural habitat. Although the general trend is an increasing of lifespan, it's practically never up to completly double it. And this rule have just too many exception to be listed. We just forget them because they're not the one we keep in captivity because of that. Evene if we count predation or infantile mortality (which cans sometime be higher in captivity due to stress).
@@PrevailingDanger - Yes I did, it speaks to broad resistance to pathogens (which include all kinds of things, not just parasites) but does not specify that many (maybe most) actively have some kind of parasite, like tapeworm for example.
After working for a water district and in the water quality department I always wondered, how many years longer did humans live once fresh water was able to be provided?
I mean, you can look at records from the days before modern water treatments. People often died very young, but if you survived your early years many lived until their 60s and 70s. Of course, early Industrial conditions resulted in a dramatic dip in life expectancy because of cholera outbreaks. nutritional deficiencies and other issues.
Maybe they can. Like when you watch a wildlife documentary, how does the narrator know the names of the animals? Like they’ll call a lioness Luna. How did they know her name? How did the lioness tell them her name?
It does. They had done statistical study on allergies bwteen city and farming community. Needless to say the kids thay grew up on farms had alot lower allergies
@@V4Now yes. coal mines, chimneys and factories! imagine the boost to GDP and reduction in crime lol. but in all seriousness, kids need to work more. household chores, apprenticeship, light manufacturing (like packaging and folding pizza boxes) and farm work.
I drank from creeks my whole childhood, never thought much of it. Then one day while hiking through western NC, I stopped to drink out of a small spring... little did I know that a handful of tourists saw me drinking from the spring and did the same.... well... the next day I was greeted by a ranger who asked me if I was ok. I was more than a little puzzled by his question and I guess he saw the look in my eyes and he then explained that they had just had to haul out 9 very sick people who had drank from a contaminated spring... Giardia was the blame he thought... .either way, I was fine... still seems wild to me, but they said they saw "another man" drinking from the same spring and that's why the ranger was out looking... I told him that I had indeed drank the water, but apparently I was either immune or didn't drink enough.... found out later from my mother that my first bout with Giardia was when I was 6 years old... IDK, what ever it was, I never got sick and have wondered if it was because I had grew up in the backwoods and drinking from creeks/springs was normal.
I'll bet you can even eat out of the trash and not get sick. In an apocalypse, you and indigenous hunter/gatherers would rule the world while all of us with weak stomachs would perish from diarrhea
I got giardia from drinking from a stream when I was 11 or 12. It jacket my system up bad for years. Honestly I blame the medication that I took to clear up the giardia for messing with my digestive system. I grew up drinking from clean rivers on the pacific north west. I was also told that once you get giardia you are more prone to get it again easily. Not sure if that's true but I have steered clear of untreated water ever since. I knew someone who got it a second time just swimming in a lake. Made me nervous because I still regularly swam in lakes and rivers.
I’ll drink from the streams too if they look clean and aren’t stagnant. I’m in NC too so have hiked lots here and along the AT. I basically live like a wild animal lol. I transitioned to going barefoot and sleeping on the ground for example and people are always asking if I’m okay lol. I’m in the best shape of my life now and don’t really get sick or at least not in the last couple years so not too concerned with unfiltered water and figure my body can fight stuff off.
@@TDONTLO I probably could. My life is pretty interesting. Social media isn’t really my strength though. Don’t do any social media and probably would’ve deleted youtube by now too if it’s not where I listen to music. Besides the very unique lifestyle changes I’ve made, I think I’m a pretty normal guy and love my same old boring routine. Live just 2-3 hours from AT and did a few week long trips growing up, but don’t hike much except the rare day or weekend trips. Tbf I’ve only tried drinking unfiltered water a couple times recently and always packed or used a filter. I like to pack light so will often just bring one water bottle in hand and nothing else for a day hike and usually finish the water by the summit. My last hike was pouring down rain so I figured that stream was as fresh as it gets. I do really want to make an impact and show to the world how beneficial a simple change of using less support in your daily life can positively affect your health like it has done mine, but for now I’m focused on just becoming a faster runner because I think actions speak louder than words. Just about every runner in my city probably knows by now about that barefoot guy which should at least get them wondering instead of blindly following the shoe narrative and then I assume getting really good at it will help my case. After 1 year I ran 20:20 for the 5k and have had some setbacks, but think I may soon be able to improve on that time as the 2 year mark draws near and then hopefully the progress continues, but it takes a lot of patience so I’m ready if I have to wait longer. If you’re still ready my blog and actually interested lol, I would recommend you look into combining both the floor sleeping and barefoot for the best results. I see both as connected in the larger umbrella of cutting out artificial support from my life. I can’t imagine having the success I’ve had running barefoot without going all in and ditching the bed too. I started doing all of this after an injury led me to a desperate visit to the chiropractor which naturally made me feel even worse from all of the support and got me sleeping on the ground instead and completely changing my way of thinking in regards to health. The feet are the foundation and very important, but I think everything is connected and the beds we use are insanely cushioned compared to modern shoes. I’d argue you’ll see bigger improvements cutting out the bed. I have to stop now lol I’m getting too fired up over beds of all things.
This is interesting. It’s analogous to when traveling abroad and if you drink from the local water source, you get stomach sickness. Until your body adapts to it.
Yes, I went to live in the Azores back in 1986 and had to get a Typhoid shot before going. I was also told about the island "crud" that hits you shortly after arriving from the water. My husband was in the military and there was a place we could go to fill water bottles for drinking but I brushed my teeth with the tap water and made coffee with it and of course, showered. You couldn't help but ingest it and I got sick for a week, stomach pains and diarrhea, it was awful. After that, I was fine, lived there 2 years without any further incident.
When I was a kid, my Mom once said to me that: "being too clean can be bad for you". This ran against all that everyone else around me said about the importance of being clean at all times. I guess she had a valid point.
It's an extremely valid point and very true. Folks who don't spend enough time outside will have extremely weakened immune systems and get sick too easily. Your body adapts to adversity, just as exercise slowly strengthens you, so too does exposure to bacteria and other microbes. The caveat is that, just like with exercise, it's only helpful if it's within the level of severity your body can handle and recover from.
But i still dont want worms in my butt. Or even worse, toxoplasmosis. My grandma worked as a doctor in a village. She had to treat ppl with huge worms couple meters in length! All because they ate with dirty hands or dirty veggies cow pooped on earlier.
she's absolutely correct. as a human, a great ape, your body just like every other species on this earth has evolved to survive outside with nothing but its own skin. your immune system is just as adaptable as any other species, and overly sanitizing your environment definitely has an adverse effect on your immune system.
@@Cricket2731 It is making a comeback because people aren't vaccinated against it anymore. When people are vaccinated, they can't get it anymore (except for super rare cases).
i grew up swimming in rivers and dams. We would literally drink that water, man we never get sick of it. You would have to visit some continents to appreciate and see for yourself what am talking about. We would share the same source with animals.
You observe a similar thing in what animals eat. When cattle switch from winter feed to summer pasture they will often show signs of mild intestinal distress while their bodies and gut flora adjust to the richer food source and potentially new bacteria and fungus exposure. When it is a regular seasonal change this is not a big deal but it can be fatal if the food source in dramatically different without allowing an adjustment. I remember learning about how the Northwest Mounted Police (now the RCMP) had problems when they started because the horses they brought west were used to tame strains of grass common in Ontario. Many horses got sick and died when exposed to the wild native grasses that were common in the prairies without a allowing a period of transition where they had a mix of grass and Ontario hay.
@rickybarber347 Generally most modern horses are like sports cars... you need to feed them premium fuel... meanwhile horses that were historically used for work were like regular cars and trucks, more tolerant of lower quality feed... which makes Oxen tractors
@rickybarber347 I have personally benefitted from this though as I have gotten good quality hay for a fair price due to it not meeting the exact standards for horse owners... in one case during a year with a hay shortage due to poor growing conditions one seller couldn't sell his hay despite being top conditions because the colour didn't match across all the bales...
Actually, we human do this all the time. Most people will get digestive problems the first time they try street food in foreign countries. However, the natives are quite ok with it. My experience, I used to be able to eat street food with no problems. After three years without street food, the day I ate it again, I exploded my toilet 🚽.
@@tranphuocloc5629 indeed, I once read a short story about the future process of preparing space born humans for a trip to Earth. The idea was that it would be a difficult process of forced exposure to Earth intestinal bacteria so that they could eat normal Earth food without dying.
I went hiking in southern Arizona and thank goodness it had rained the day before. Luckly, the area I hiked in had a decent size stream, waist high, that was flowing, as I didn't bring enough water and started over-heating (hyperthermia + dehydration) and had to get in the stream & drink from it. I didn't get ill or contact any pathogens (it's been over 20 years). That stream saved my life.
Parasites are not that harmful to our health. Some scientific studies these days have shown they act like the way the bacteria do to our body as probiotic.
There are two points I want to bring up. 1) Animals don't want to appear weak to predators and so either don't show their illnesses much or hide if it gets bad. That's why seeing a sick animal out in the wild is such a big deal because it usually means it's in the fatal stages of whatever disease it has such as rabies. 2) While I get the point of most animals getting naturalized to their local pathogens, this doesn't as easily explain animals that travel vast distances through various biomes. Specifically migratory birds, whales, and fish such as salmon or eels. Bats are a whole different thing because their immune system is so odd.
It is not just animals. People can get used to drinking dirty water too. Lot of countries don't have safe public water supply. People develop immunity to pathogens but sometimes it can backfire. There is natural selection at play everywhere you turn.
Believe it or not human stomach acid is way stronger. After hyena and vultures ours is basically the strongest, which is what lead scientists to hypothesise we used to be scavengers, just after we evolved bi-pedalism and won’t so quick in our feet yet
Raw meat isn't inherintly dangerous. It's when it's been sitting around is when it gets dangerous such as when beef hangs in a refrigerator for weeks/months. Carnivores don't eat rancid meat.
Oh they do got sick, they’re not the only one who adapt, their pathogens also adapt. Parasites are often tout to play a role in the balance of the ecosystem by keeping the host’s population in check.
Not really. Parasites are parasites. There's no good in them. Predators and prey keep themselves in balance. Lots of food = lots of animals -> rise in predators -> low amount of prey -> fall of predators. It's a cycle of predators and prey.
And they often die from diseases and parasites as well . Some people really think that animals somehow live a long and healthy life ; they mostly don't.
I visited a town in Southern Luzon in the Philippines called Prieto Diaz. It was absolutely beautiful, with pristine beaches and mangrove forests... and the highest concentration of microbes in the drinking water of anywhere I've ever been. Unfortunately I didn’t know this until I had already drank it, but I was amazed that what caused me major distress didn’t seem to bother the people who lived there their entire lives.
Wildlife still carry impressive loads of parasites though. Studies have been done in ducks, bears, and wild canids. They can carry multiple species of parasite at once, and shed them with their frequent loose stools. Wildlife, like domestic animals and humans, still benefit from clean drinking water when living at zoos, preserves, etc. They survive out there, and would rather be free, but can actually be healthier in some ways in captivity.
Yep, inportant bit: animals do get sick (and die), we just don't notice it. People can "get used to" dirty water too, but again, will get sick or die from it eventually (or quick if the water has the wrong germs). Animals get traveler's gut just like people do if they move long distances, they just don't move long distances outside of migration. Migratory birds don't really get used to local bacteria because they move around so much, but their higher body temperature protects them from most pathogens.
George Carlin said it best!!! Our Immune Systems need PRACTICE!!! There is something to be said about how some of us drank out of a Garden Hose growing up and just washed off a scratch, with maybe some Iodine and a Bandage included…then went back outside to play the rest of the day!!!
I remember drinking water in New Zealand on a hike, , I wasn’t sure of it’s source so it was a stupid thing to do. I filled up my bottle where it was flowing and immediately after I drank I new I was in trouble. What followed was a week of the mist horrendous brain sickness I have ever felt. Like a migraine x1000, I thought I was going to die for sure. Went to hospital even but nothing could be done. My body eventually conquered it, but it was close. May a type of encephalitis.
That is terrifying. And New Zealand of all places. I swear that would have been one of the last places I'd have guessed. Definitely taking a life straw with me everywhere on hikes, jesus. Cursory research points to it maybe being Primary meningoencephalitis, an amoebic infection that is found in untreated geothermal pools in NZ. It is almost always fatal. I suppose, if that was what you contracted, it may have entered the waterways from outflow leaving the thermal pools. Of course, I'm not a scientist, I'm just guessing.
Those can be annoying at time but deep dives can also be very interesting especially if you’re playing them while doing another task. Sometimes I watch them while doing chores and it makes them less boring
And it's SO obvious too. To their intro will sound like "This thing is so incredible and caused so many other problems. What an awful thing, that thing is. What is this thing? Let's talk about 3 other things before we state the obvious in 25 minutes 😵🙄@@ProckerDark
Their body has adapted to it since it's what they, and their ancestors, have grown up with. Animals do still get sick though, especially if it's something they're not adapted to. They just don't tend to lay out in the open when they're sick so that predators, people, and/or cameras can pick them out easily. You're probably never going to know if they puke their guts out or drop dead in a cave or bush somewhere.
This video correctly points out that it's the microorganisms that are the problem. Believe it or not, there are some people out there who believe it's the "dirt" in the water that causes health problems. This is not the case, and I saw it firsthand when I was in rural provinces in the Philippines. In poor areas, most people don't have wells and frequently there are no water lines. If you want water in these areas, you stand in line with a container -- sometimes for hours -- at one of the barangay's pumps. Obviously you're getting ground water, so it's likely safe from germs. But in the summer months (April and May, for example), the ground water levels decrease. And what comes out looks dirty. But they drink it and don't get sick. So, it's fine -- although I'm told it tastes bad.
@@jetla22Your question is even dumber, but let me answer it. That dirty water has bacteria and parasites unique to it, so even with the other less-than-ideal factors like you mentioned, raw meat and blood, dirty water brings in its own complications that also shorten the animals' lifespans. This is why captive animals live longer and healthier lives.
I drink pond water so I’m still alive i got sick a little but now I’m not but many kids have survived from drinking it so you will not die if drink a little
Very enlightening video. I always wondered this. I guess then that human's privileged access to consistent cleaning drinking water has essentially eliminated most of us from surviving in the wild just on water access alone. Also, as the video pointed out, animals can still get sick from contaminated water. They then tend to hide away to die or recover on their own. They aren't able to communicate that they're ill or in discomfort so well either. Also, as others pointed out, many wild animals don't live that long due to such constant physical stresses presuming they don't fall prey to predators too.
Nope. You could go out there and drink from that dirty pond. You'd almost certainly get ill for a while, but probably not dead (if you're an otherwise healthy adult with adequate nutrition). And then your immune system would get used to it (of course with the added parasite load you'd have - but so do most wild animals and so do most humans living in less industrial societies). Billions of people live with unclean water sources. They don't die overnight. People from the first world travel to these countries all the time, eat the food, drink the water. They get sick, but actual death is still rare. What happens down the road if you continue drinking from the same source depends on whether or not you're unlucky enough to get stressed or injured or malnourished enough to reduce your immune system's effectiveness and get seriously (life threateningly) ill. Or another infection from another source damages your immune system and does the same job. Risks of a lot of future diseases go up to varying degrees (though, paradoxically, a few go down like the autoimmune illnesses). Otherwise, you'd probably live for quite some time drinking contaminated water without further serious risk to health.
It’s like my wife said to me when dating. She live in the mountains in PR and her family had what I think was questionable well water. She told me that if I drink the well water I will get sick. She and her family all drank the water and appeared in very good health and always drank Her grandmother were 80+. I drank the water and got sick for a couple of week but it got better and a month later is was like nothing happened. Never had a problem with that water again. That was 40 years ago and still no problems.
Interesting fact: In medieval Europe, they knew that drinking tainted water could make someone sick. This was long before any scientific knowledge of microbes. To avoid illness, they brewed a low alcohol content beer and drank that more commonly than water alone.
You missed a crucial point. ANIMALS DO GET SICK!! Animals in captivity live significantly longer lives than animals in the wild because of this. Dying in your prime from parasites is normal in the animal kingdom. And when humans used to drink from water sources like this, they too would die in their 30s and 40s and that was normal. Drinking from safe water sources has extended our lifespan and extends the lifespan of animals too.
I drank from a natural spring in a central Texas park. I don't remember the name, but I probably have something in me still. This was in the 90's. But it looked so clear and cold on a summer's day. Water never tasted so good.
I used to frequent a farm in England that got their water from a spring, it wasn't crystal clear, it looked kinda manky actually, but goddamn that was some good tea.
@@memitim171 well, bacteria-infested water is generally okay for making tea. As long as the water stays at boiling temperature for a suitable length of time, the bacteria will no longer be a concern.
I was not expecting the comments of this video to be full of people admitting to still drinking very gross water, and not believe in handwashing. This is weird
Good question 😊 I've drank from seemingly pristine mountain streams and got deathly ill. I think there is more to the story, such as stomach acidity. I do not agree that immunity is the only answer.
The only thing that's weird is that humans did live in "the wild" not long ago and, in fact, still do in some places. So I'm confused about how we didn't also evolve to be more resilient to water illnesses.
We did, and then people that got sick immediately died. Never passing on the inferior genes. But once we got clean water for hundreds of generations after mutations form and sort of scramble the immunity that we once had. And since we aren't drinking bad water anymore there's no way to filter out those bad mutations. And after enough generations those mutations build up and put us back to square one.
well, we did, kinda of. evolution works in both directions, so as our immune systems get better at detecting and destroying the various microbes in the water, the microbes get better at evading our detection, and better at using the resources within our bodies. since human and most other animals live much longer than most microbes do, the organisms that get us sick have many, *many* more generations across which evolution takes place. so say for every 1 average mouse lifetime, there's been 100,000 generations of amoeba that have lived, died, and sometimes changed slightly. really the whole thing is just an arms-race between big animals and tiny microbes where the animals are outpaced by a few orders of magnitude
@@Stikstaour water has not been potabilized for "hundred of generations". And, as the video explains, adaptive antibody resistance is built over an organism's lifetime, with repeated exposure. It's not genetic.
you rely WAY too much on the meme of muh "multiple generational adaptation theory". That barely accounts for half the things explainable today and is usually used as a "give all" answer. If what you say is true then why hasn't our gallbladders or appendixes been completely removed from our system? Obviously we do not eat the same things as our monkey ancestors ate so why do we still have it? Muh "multiple generations theory" holds exactly ZERO water (pun intended).@@Stiksta
@@santiagoacosta777 building immunity is still relative to ones genes. We all build our immunity to different strengths and some individuals cant build one even with a healthy life style and consistant exposure to germs. This Basic principle is better explained in a micro biology class. But Humans are becoming weaker in general due to our advance society. Another example would be our mouths becoming smaller thus having the issue of removing teeth/crooked teeth. Our food is too soft, and refined so we are now haveing dental issues and weaker jaws.
2:29 This... doesn't actually apply to all maybe even most humans, only people in developmed countries. Great video! But its interesting how quickly we'll forget there's entire countries full of people whom this literally isn't a reality.
@@missd411 I'm not sure, but I've been to poorer and wealthier localities in Haiti, and none that i visited had running water that was treated (filtration and/or chlorination). Very common, though, to see places selling RO treated water in plastic containers.
In Shona culture of Zimbabwe it was a practice that when a baby was born to give him water from the local RIVER not well as soon as possible and then as she got older have them lick or put the sand from the village compound and chew the leaves It was our way to expose them very early to local pathogens and when you visited a new area you first had to drink the local water That way we had iron strong immunities
Except diarrhea and vomiting in babies can be so much more drastic because babies have a low surface to volume and can't afford to lose water that quickly. Biggest killer of babies in the world, seems like a big risk but the Shona have been doing it a long time i'll bet.
I have always been jealous of animals that can eat & drink almost anything: My local crows for example - feasting on week-old road kill and then taking a sip from a contaminated mud-hole.
When I was a rurally-raised kid, giardia ("beaver fever," a parasitic infection linked to infected drinking water) was considered normal part of childhood - like chicken pox or teething pains. Indeed, it was thought best to "get it out of the way" while the child is still in diapers. This wasn't just because of the associated diarrhea, but also because of a widespread folk belief that, once one had giardia, one has it for life. It was thought that, after a couple weeks of discomfort, the body adapted to the microbes, which stayed with the host from then on - a fortunate thing, since one was likely to ingest more of them whenever drinking from a natural source in beaver country. In true fact, the protozoa that cause giardia only live part of their life cycle in a human host. They mature in the body and replicate there, but the young are pooped out and the mature protozoa die off. However, it's an observable fact that people who have had giardia and "gotten used to it" are rarely troubled by the tummy-discomfort and other symptoms afterward. Antibodies and immunity are something we generally associate with viruses, but it seems like there must be some sort of acclimation to giardia. Of course, there is also emerging evidence that giardia infections may be a factor in arthritis, Crohn's disease and a few other maladies - but the jury is out on the full story about this, and whether it matters whether a person has been infected once or many times through their life.
Buddy I am from Haiti and in a poor community in my childhood, now I live in Dominican Republic I used to drink dirty water from the river everyday so human adapt too. in DR I drink water from faucet once in a while to keep my immunity.
I came across instructions for making a device to filter water from a plastic bottle with layers of charcoal and sand.. I think you're supposed to boil it before drinking it tho. It's supposed to work even for "pond water". Personally I wouldn't try it near the chemical plant.
Also, wild animals don't live all that long. Their lives are brutal and short. Parasites limits their lifespans hugely. A cat can live 15 or more years domestically.... in the wild they very rarely get past 7 years.
@@prettynoose888 Every wild animal lives longer sometimes twice as long on avarage in captivity. I am not saying that keeping them in captivity for no reason is good, but they do live alot longer there.
There's a reason why we de-worm our cattle at least once a year, even though the water they drink is clean. If one of our cows get's sick, we treat them appropriately. If a wild animal get's too sick, it dies. Because we are caretakers, we can extend the life and comfort of our livestock when it comes to sickness such as that from water sometimes.
Contaminated water in the wilderness is a relatively new development. I was born in 1966 and was an avid hiker and backpacker. We went hiking nearly every weekend with friends and in boy scouts and none of us had ever even heard of a backpacking water filter. None of us ever got sick and we always drank right from the streams and springs. It was about the time I got to high school that we even heard of waterborne illnesses.
Nowadays with modern technology, an animal may die upstream and contaminate the water. Back before technology, dead animals near water would float up into the sky and disappear instead of rotting in the water... Hmmm... Sounds fishy to me.
To put it simply: when an animal is born and gets exposed the water's bacteria ot either gets sick and dies or its body manages to fight it off and survive... The ones that survive breed and pass on their good immune system to ensure their offspring are safe... Well not ensure just increase the chances that is And yes they do get sick especially as they get older and their bodies become weaker which is why its very rare to have a long lived wild animal
Humans have the same immunity. You’ve heard of Delhi Belly, people from other countries eat or drink in foreign countries and they get very sick, but natives from that region can eat or drink the very same thing and are not affected.
I had friends who had an old cistern at their house. They had gotten municipal water but I guess at one point that was the water source for the home. It collected rainwater runoff into what looked like a concrete hole. Anything could have crawled in there and died. I hope they had some way to filter it back in the day.
However, we've had firecraft for the greater part of a million years. That will really change the biology of a lifeform. We are essentially adapted to using fire to cook our food and boil our water. Tbh, I've got a theory that it's why we think woodsmoke smells wonderful, while any other animal dips out as fast as possible.
They're used to it, but still they live short lives in the wild. You don't see very many sick animals in the wild because they're already dead. As poor as the food is for cats and dogs, they'll still far outlive their feral counterparts. Humans were able to source cleaner water, so they lost much of their resistance to pathogens.
People are animals as well and adapt to our food/water sources the exact same way. I surely wouldn't go to Mexico and drink the water 😅but I did have a boss involved in the oil field who made trips to Mexico very regularly and he was able to drink their water without getting sick.
@@BonaparteBardithion Come on dude. We are talking severe diarrhea that could kill you when you travel to a third world country. And the locals look at you like "look at that soft boy from the rich country lol" Not upset stomach from different mineral composition.
@@sagnorm1863 I'm not saying it's on the same scale, just that it's the same basic concept to a different extreme. It's all about what you're acclimated to. And even in first world countries water quality can vary widely depending on where you are. There are people in the same town as me that won't drink tap water because of the pipe conditions in their neighborhood.
Natural selection is more of a social experience rather than a physically imposed one. You can live having lost body parts, nowadays, live as long as the wealthiest back then@@junahsong130
People also can't be outside getting wet & cold as they risk getting pneumonia, but wild animals can. The more you pamper people the less they can handle. The same goes for spelling & grammer & math. Once you let programs do the work you begin to lose the ability to do them without assistance.
Animals actually can get sick when drinking contaminated water from puddles, lakes and rivers as it all comes down to what’s in the water as opposed to how murky is it but those who developed a resistance to the contaminants are likely to survive.
It's also for the same reason that a human's mouth is dirtier and we have to brush our teeth daily and animals never need to. Most humans are addicted to food and sugar which feed the bacteria and gets out of control. Whereas eating 1-2 meals a day our body would adapt by increasing HGH and we'd need fewer calories per day. We've also taken antibiotics for generations which is reducing our microbiome biodiversity. If only most humans knew about these issues.
Short answer: Animals are just built different. They're adapted to a life in the wild, while we have adapted to luxuries. Homosapiens and other prehistoric humans were also like this, consuming water from dirty lakes, ponds or rivers. But of course, I'm no expert or a scientist, please correct me if I'm wrong. I'm just a guy who wants to learn more about animals, both extinct and living. Have a great day.
You're not wrong, but consider you're throwing a die every time you expose yourself to dangerous pathogens. So the safest play is to not expose yourself to them if you can avoid it... Yeah, yeah, I know: "what's considered dangerous?", it's a chicken or the egg conundrum.
Its not really that they're built different, its that their resistance to parasites and pathogens are being constantly tested, and we tend to only see the animals that survive
@@robinator789Also we too have this resistance/resilience but our it not often used and it not as strong as other animals,you can still eat/drink food/water with bacteria and most probably be fine if you are not doing so often but be careful with that.
Another factor is that Americans have generally bad genes for dealing with contaminated water. Over here in Germany, we have springs in the wild where you can drink while hiking. Of course, there are people over here as well who cannot, but most can. We had two Americans come over for a student exchange and both got sick like dogs drinking that water even though for most Germans it is officially considered clean water.
It sounds more like dirty water that people are used to and resilient to the diseases in it. So when a foreigner (those poor Americans) drank it. They got sick. They simply do not have the resilience to the pathogens in that water.
American is a nationality, not a race or ethnicity--there are no "American genes" so that's not really what's happening. If they were white Americans they had European genes, but their immune system was not familiar with the local pathogens of the region
I basically lived outside for years. Drank from puddles, rivers and lakes when it was extremely hot out. Never got sick thankfully. I found a fresh spring coming out of a cliff once. Best water I've ever had.
I have drank water from creeks, mountain springs, lakes , rivers, wells, ponds etc etc and never got stomach problems.. I do sometimes get respiratory problems while drinking water from a new place..
The same reason we used to drink out of garden hoses and not get sick. The same reason we grew up swimming in the duck pond and yes, swallowing the water, and not get sick. The same reason we played in mud puddles on the streets and not got sick. The immune system is an amazing thing. And living in a sterile, safe environment isn't conducive to having a healthy immune system. People today are weak. Period.

One of the major contributors to illness in humans caused by water-borne pathogens is human activity. So many of the recorded plagues i recorded history were enabled by humans living in such close proximity and in such big numbers without proper sanitary precautions. People would empty their chamber pots onto the streets every morning, which inevitably ended up contaminating the local water supply. In the wild , well-oxygenated rivers populated with abundant and healthy aquatic flora do a pretty good job of keeping themselves clean, as long as they dont get overwhelmed by pathogens like humans have done in urban settings for centuries. That's basically how chlorine-free swimming pools work. The biggest contributor to human life expectancy wasn't the eradication of smallpox or any other medical advances, it was our ability to produce and distribute clean and safe drinking water at will.
Humans can actually still drink any water to some degree. The commercial one we use, which is 99% filtered is safe obviously but in places that are not commercialized or far away from civilization, unfiltered water that is 75% to 90% pure can make humans more resilient because the body adapts to it. So which is why people who drinks the filtered their whole life, will definitely feel something from unfiltered ones. While those who adapted, can drink on both types of water.
Both! It depends on the strain your body is exposed to! For example there are some pretty harmless salmonellas, but there is also a really aggressive one: just 7 of this tiny guys can make you severely ill! As a master of confectionery i once took a tiny taste of a raw uncooked cheese cake and got the worst illness of my life: shitting and vomiting for three days on a row! I nearly had to go to a hospital, it was absolutely horrible! No more unheated food with raw eggs for me! NEVER EVER!
Thank you so much, I’ve always wondered about this and am slightly annoyed I didn’t work it out for myself. Also, lovely and brief, very little fluff, outstanding content 👍
The thing is humans can drink that water too even for years and years, it's just a rare chance for a living being to get a lethal amount of pathogens in their system, a few bacteria wouldn't make it far, but a few thousand would survive and spread.
I used to work with a man who had emigrated to Canada from Mexico. He said that his children could visit the town in Mexico where he was from, drink the water, and not get sick, even though they’d never been there before, while a person from anywhere else would get sick from drinking the water. I asked him if his children were breast fed and he said yes. Mystery solved.
That's pretty common. The local population, like wildlife, become mostly accustomed to the local virus and bacterial flora. At low concentrations there may be no problem, but outsiders, that's a different story. I paid dearly for that reality in the Dominican Republic.
"This one guy I knew said his children were like this strong and big and cool and so I asked him this random question about whether or not they were breastfed and he said yes so that must mean breastfeeding is proven to be better."
Like it's shown in the video, humans have become dependent from modern technology in the developed world: without it they would mass die and the humans in developing world that are dependant from first world medicine and food exports would mass die too. Human population would quickly go back to few hundreds millions or even less in a post-industrial world, while wild animals would thrive even more.
One thing you forgot to mention is that human digestive systems also adapt to the presence of certain bacterial colonies in their area and depend on them to be properly balanced in much the same way that the animals do. Long before purified water became available, there were bacterial contaminants in the water. A typical human digestive tract can contain many different species of bacteria. Some bacterial species are actually beneficial to humans, for instance, there are bacteria that digest milk solids in the gut and have sufficient numbers to convert a normal dietary intake of milk solids into gas or beneficial byproducts that the bacteria release when digesting the milk solids.
Animals definitly have a stronger tolerance for dirty water, but thet are still picky. They will choose cleaner water (compared to dirty sagnant pools for example) if available and they will avoid certain contaminanted waters, even in a drought. They have a pretty good understanding of whats safe for them to drink and whats not.
The BIG point people miss is that by limiting ourselves to pure water for generations, we are weakening out species immune system - drastically! And we get more extreme every decade. When I was young and hiking in the Cascades, it was assumed that most drinking water from any long hike would simply be scooped up from any of the numerous streams we would cross, and no one thought twice about drinking from a clear, fast-moving stream. Paranoia has taken over - and adaptation is busy justifying it....
You were lucky. The "freshest" mountain streams can be loaded with pathogen. Debilitating disease like Giardia pre exist our presence in the "Wild Cascades" and are spread by other wildlife. As long water can flow from a point of contamination to a water body there is a risk. Type 2 errors suck.
The technology that allows us a continuous supply of clean water is a double-edged sword, it's great when it works but being so dependent on it has one major drawback.

The important bit here is that animals generally live half as long in the wild than in captivity. If they get weakened from illness injury or age those pathogens, parasites will absolutely kill wild animals.
Actually lot of them don't live longer in captivity.

@@deinsilverdrac8695 lol wrong, there's literally scientific studies and observations that captive raised animals live longer and are healthier then their relatives in the wild, dying from predators, diseases, parasites, pollution, poaching, and not enough food, there's a lot of reasons why wild animals love shorter lives lol
@@adam-kyup, this guy has the right of it

And actually a lot of species can't be kept in captivity because they die quickly out of their natural habitat.
Although the general trend is an increasing of lifespan, it's practically never up to completly double it.
And this rule have just too many exception to be listed.
We just forget them because they're not the one we keep in captivity because of that.
Evene if we count predation or infantile mortality (which cans sometime be higher in captivity due to stress).

I drank from creeks my whole childhood, never thought much of it. Then one day while hiking through western NC, I stopped to drink out of a small spring... little did I know that a handful of tourists saw me drinking from the spring and did the same.... well... the next day I was greeted by a ranger who asked me if I was ok. I was more than a little puzzled by his question and I guess he saw the look in my eyes and he then explained that they had just had to haul out 9 very sick people who had drank from a contaminated spring... Giardia was the blame he thought... .either way, I was fine... still seems wild to me, but they said they saw "another man" drinking from the same spring and that's why the ranger was out looking... I told him that I had indeed drank the water, but apparently I was either immune or didn't drink enough.... found out later from my mother that my first bout with Giardia was when I was 6 years old... IDK, what ever it was, I never got sick and have wondered if it was because I had grew up in the backwoods and drinking from creeks/springs was normal.
I'll bet you can even eat out of the trash and not get sick. In an apocalypse, you and indigenous hunter/gatherers would rule the world while all of us with weak stomachs would perish from diarrhea
I got giardia from drinking from a stream when I was 11 or 12. It jacket my system up bad for years. Honestly I blame the medication that I took to clear up the giardia for messing with my digestive system. I grew up drinking from clean rivers on the pacific north west. I was also told that once you get giardia you are more prone to get it again easily. Not sure if that's true but I have steered clear of untreated water ever since. I knew someone who got it a second time just swimming in a lake. Made me nervous because I still regularly swam in lakes and rivers.
I’ll drink from the streams too if they look clean and aren’t stagnant. I’m in NC too so have hiked lots here and along the AT. I basically live like a wild animal lol. I transitioned to going barefoot and sleeping on the ground for example and people are always asking if I’m okay lol. I’m in the best shape of my life now and don’t really get sick or at least not in the last couple years so not too concerned with unfiltered water and figure my body can fight stuff off.
@tommy7467 you gotta start a vlog my guy lol I'd watch everyday
@@TDONTLO I probably could. My life is pretty interesting. Social media isn’t really my strength though. Don’t do any social media and probably would’ve deleted youtube by now too if it’s not where I listen to music. Besides the very unique lifestyle changes I’ve made, I think I’m a pretty normal guy and love my same old boring routine. Live just 2-3 hours from AT and did a few week long trips growing up, but don’t hike much except the rare day or weekend trips. Tbf I’ve only tried drinking unfiltered water a couple times recently and always packed or used a filter. I like to pack light so will often just bring one water bottle in hand and nothing else for a day hike and usually finish the water by the summit. My last hike was pouring down rain so I figured that stream was as fresh as it gets. I do really want to make an impact and show to the world how beneficial a simple change of using less support in your daily life can positively affect your health like it has done mine, but for now I’m focused on just becoming a faster runner because I think actions speak louder than words. Just about every runner in my city probably knows by now about that barefoot guy which should at least get them wondering instead of blindly following the shoe narrative and then I assume getting really good at it will help my case. After 1 year I ran 20:20 for the 5k and have had some setbacks, but think I may soon be able to improve on that time as the 2 year mark draws near and then hopefully the progress continues, but it takes a lot of patience so I’m ready if I have to wait longer. If you’re still ready my blog and actually interested lol, I would recommend you look into combining both the floor sleeping and barefoot for the best results. I see both as connected in the larger umbrella of cutting out artificial support from my life. I can’t imagine having the success I’ve had running barefoot without going all in and ditching the bed too. I started doing all of this after an injury led me to a desperate visit to the chiropractor which naturally made me feel even worse from all of the support and got me sleeping on the ground instead and completely changing my way of thinking in regards to health. The feet are the foundation and very important, but I think everything is connected and the beds we use are insanely cushioned compared to modern shoes. I’d argue you’ll see bigger improvements cutting out the bed. I have to stop now lol I’m getting too fired up over beds of all things.
This is interesting. It’s analogous to when traveling abroad and if you drink from the local water source, you get stomach sickness. Until your body adapts to it.
Better to drink alcoholic beverages then.
This should not happen in first world countries. At worst a higher level of chlorine than one is used to.
Dont you have a filter on kitchen at least?
Yes, I went to live in the Azores back in 1986 and had to get a Typhoid shot before going. I was also told about the island "crud" that hits you shortly after arriving from the water. My husband was in the military and there was a place we could go to fill water bottles for drinking but I brushed my teeth with the tap water and made coffee with it and of course, showered. You couldn't help but ingest it and I got sick for a week, stomach pains and diarrhea, it was awful. After that, I was fine, lived there 2 years without any further incident.
Both Mexico and the Dominican Republic gave me gastrointestinal issues.
When I was a kid, my Mom once said to me that: "being too clean can be bad for you". This ran against all that everyone else around me said about the importance of being clean at all times. I guess she had a valid point.
It's an extremely valid point and very true. Folks who don't spend enough time outside will have extremely weakened immune systems and get sick too easily. Your body adapts to adversity, just as exercise slowly strengthens you, so too does exposure to bacteria and other microbes. The caveat is that, just like with exercise, it's only helpful if it's within the level of severity your body can handle and recover from.
It depends on how clean or how dirty
Moderation is good here too
But i still dont want worms in my butt. Or even worse, toxoplasmosis. My grandma worked as a doctor in a village. She had to treat ppl with huge worms couple meters in length! All because they ate with dirty hands or dirty veggies cow pooped on earlier.
she's absolutely correct. as a human, a great ape, your body just like every other species on this earth has evolved to survive outside with nothing but its own skin. your immune system is just as adaptable as any other species, and overly sanitizing your environment definitely has an adverse effect on your immune system.

i grew up swimming in rivers and dams. We would literally drink that water, man we never get sick of it. You would have to visit some continents to appreciate and see for yourself what am talking about. We would share the same source with animals.
You observe a similar thing in what animals eat. When cattle switch from winter feed to summer pasture they will often show signs of mild intestinal distress while their bodies and gut flora adjust to the richer food source and potentially new bacteria and fungus exposure. When it is a regular seasonal change this is not a big deal but it can be fatal if the food source in dramatically different without allowing an adjustment.
I remember learning about how the Northwest Mounted Police (now the RCMP) had problems when they started because the horses they brought west were used to tame strains of grass common in Ontario. Many horses got sick and died when exposed to the wild native grasses that were common in the prairies without a allowing a period of transition where they had a mix of grass and Ontario hay.
The cops should have known better, poor beasts.
@rickybarber347 Generally most modern horses are like sports cars... you need to feed them premium fuel... meanwhile horses that were historically used for work were like regular cars and trucks, more tolerant of lower quality feed... which makes Oxen tractors
@rickybarber347 I have personally benefitted from this though as I have gotten good quality hay for a fair price due to it not meeting the exact standards for horse owners... in one case during a year with a hay shortage due to poor growing conditions one seller couldn't sell his hay despite being top conditions because the colour didn't match across all the bales...

Luckly, the area I hiked in had a decent size stream, waist high, that was flowing, as I didn't bring enough water and started over-heating (hyperthermia + dehydration) and had to get in the stream & drink from it. I didn't get ill or contact any pathogens (it's been over 20 years). That stream saved my life.
Yooo shout-out to that stream that saved onenikkione👀👏👏
It’s amazing how precious water really is!
Parasites are not that harmful to our health. Some scientific studies these days have shown they act like the way the bacteria do to our body as probiotic.
If there was pathogens in the water they would be non genetically modified man made ones which cause no harm nor cannot cause harm
Dont forget you can always boil your water before drinking it to ensure its safe to drink in a pinch.
There are two points I want to bring up. 1) Animals don't want to appear weak to predators and so either don't show their illnesses much or hide if it gets bad. That's why seeing a sick animal out in the wild is such a big deal because it usually means it's in the fatal stages of whatever disease it has such as rabies. 2) While I get the point of most animals getting naturalized to their local pathogens, this doesn't as easily explain animals that travel vast distances through various biomes. Specifically migratory birds, whales, and fish such as salmon or eels. Bats are a whole different thing because their immune system is so odd.
It is not just animals. People can get used to drinking dirty water too. Lot of countries don't have safe public water supply. People develop immunity to pathogens but sometimes it can backfire. There is natural selection at play everywhere you turn.
They eat raw meat covered in filth, bodily fluids, and flies. That gastric acid can probably kill anything on the spot 😅
Gastric acid is not what will save you if a resistent intestinal pathogen enters your body.
The worms will feast
Believe it or not human stomach acid is way stronger. After hyena and vultures ours is basically the strongest, which is what lead scientists to hypothesise we used to be scavengers, just after we evolved bi-pedalism and won’t so quick in our feet yet
Raw meat isn't inherintly dangerous. It's when it's been sitting around is when it gets dangerous such as when beef hangs in a refrigerator for weeks/months. Carnivores don't eat rancid meat.

Oh they do got sick, they’re not the only one who adapt, their pathogens also adapt. Parasites are often tout to play a role in the balance of the ecosystem by keeping the host’s population in check.
And some literally have incorporated themselves into our biome.
Not really. Parasites are parasites. There's no good in them.
Predators and prey keep themselves in balance. Lots of food = lots of animals -> rise in predators -> low amount of prey -> fall of predators. It's a cycle of predators and prey.
And they often die from diseases and parasites as well . Some people really think that animals somehow live a long and healthy life ; they mostly don't.

Agreed. I love finding absolute gems like these and binge watching their content.
Wildlife still carry impressive loads of parasites though. Studies have been done in ducks, bears, and wild canids. They can carry multiple species of parasite at once, and shed them with their frequent loose stools. Wildlife, like domestic animals and humans, still benefit from clean drinking water when living at zoos, preserves, etc. They survive out there, and would rather be free, but can actually be healthier in some ways in captivity.
Also: Brown water is not unhealthy! Its not very nice to drink sandy water, but perfectly safe if fresh.

Animals get traveler's gut just like people do if they move long distances, they just don't move long distances outside of migration. Migratory birds don't really get used to local bacteria because they move around so much, but their higher body temperature protects them from most pathogens.

What followed was a week of the mist horrendous brain sickness I have ever felt.
Like a migraine x1000, I thought I was going to die for sure. Went to hospital even but nothing could be done.
My body eventually conquered it, but it was close. May a type of encephalitis.
You had strong enough genes.
I make sure to drink just enough to not die of dehydration in these times
How did you know immediately that you were in for a bad time?
That is terrifying. And New Zealand of all places. I swear that would have been one of the last places I'd have guessed. Definitely taking a life straw with me everywhere on hikes, jesus.
Cursory research points to it maybe being Primary meningoencephalitis, an amoebic infection that is found in untreated geothermal pools in NZ. It is almost always fatal.

Their body has adapted to it since it's what they, and their ancestors, have grown up with. Animals do still get sick though, especially if it's something they're not adapted to. They just don't tend to lay out in the open when they're sick so that predators, people, and/or cameras can pick them out easily. You're probably never going to know if they puke their guts out or drop dead in a cave or bush somewhere.
This video correctly points out that it's the microorganisms that are the problem. Believe it or not, there are some people out there who believe it's the "dirt" in the water that causes health problems. This is not the case, and I saw it firsthand when I was in rural provinces in the Philippines. In poor areas, most people don't have wells and frequently there are no water lines. If you want water in these areas, you stand in line with a container -- sometimes for hours -- at one of the barangay's pumps. Obviously you're getting ground water, so it's likely safe from germs. But in the summer months (April and May, for example), the ground water levels decrease. And what comes out looks dirty. But they drink it and don't get sick. So, it's fine -- although I'm told it tastes bad.
"Why don't they get sick" - Those who do are dead...
What a dumb question. They eat flesh and blood. Wtf dirty water gonna do lol
I too miss natural selection
@@jetla22Your question is even dumber, but let me answer it. That dirty water has bacteria and parasites unique to it, so even with the other less-than-ideal factors like you mentioned, raw meat and blood, dirty water brings in its own complications that also shorten the animals' lifespans. This is why captive animals live longer and healthier lives.
I drink pond water so I’m still alive i got sick a little but now I’m not but many kids have survived from drinking it so you will not die if drink a little
I drank tap water and started felling better but I wish I was invincible
I always wondered about this, and it follows what I suspected.
This video was very well done!
Very enlightening video. I always wondered this. I guess then that human's privileged access to consistent cleaning drinking water has essentially eliminated most of us from surviving in the wild just on water access alone.
Also, as the video pointed out, animals can still get sick from contaminated water. They then tend to hide away to die or recover on their own. They aren't able to communicate that they're ill or in discomfort so well either.
Also, as others pointed out, many wild animals don't live that long due to such constant physical stresses presuming they don't fall prey to predators too.
Humans do have the advantage of being able to use fire to boil water - which can be done in the wild with relatively basic resources
Nope. You could go out there and drink from that dirty pond. You'd almost certainly get ill for a while, but probably not dead (if you're an otherwise healthy adult with adequate nutrition). And then your immune system would get used to it (of course with the added parasite load you'd have - but so do most wild animals and so do most humans living in less industrial societies). Billions of people live with unclean water sources. They don't die overnight. People from the first world travel to these countries all the time, eat the food, drink the water. They get sick, but actual death is still rare.
What happens down the road if you continue drinking from the same source depends on whether or not you're unlucky enough to get stressed or injured or malnourished enough to reduce your immune system's effectiveness and get seriously (life threateningly) ill. Or another infection from another source damages your immune system and does the same job. Risks of a lot of future diseases go up to varying degrees (though, paradoxically, a few go down like the autoimmune illnesses). Otherwise, you'd probably live for quite some time drinking contaminated water without further serious risk to health.
Privileged? We worked our asses off to achieve clean drinking water. Quit calling amazing feats of progress “privilege”.

It’s like my wife said to me when dating. She live in the mountains in PR and her family had what I think was questionable well water. She told me that if I drink the well water I will get sick. She and her family all drank the water and appeared in very good health and always drank Her grandmother were 80+. I drank the water and got sick for a couple of week but it got better and a month later is was like nothing happened. Never had a problem with that water again. That was 40 years ago and still no problems.
Interesting fact: In medieval Europe, they knew that drinking tainted water could make someone sick. This was long before any scientific knowledge of microbes. To avoid illness, they brewed a low alcohol content beer and drank that more commonly than water alone.
Even senior citizens can develop a high tolerance to spoiled food if they get exposed to enough times.

You missed a crucial point. ANIMALS DO GET SICK!! Animals in captivity live significantly longer lives than animals in the wild because of this. Dying in your prime from parasites is normal in the animal kingdom. And when humans used to drink from water sources like this, they too would die in their 30s and 40s and that was normal. Drinking from safe water sources has extended our lifespan and extends the lifespan of animals too.

I drank from a natural spring in a central Texas park. I don't remember the name, but I probably have something in me still. This was in the 90's. But it looked so clear and cold on a summer's day. Water never tasted so good.
Probably had mad minerals and electrolytes. Your nutrient sensing receptors must have been lighting up.
I used to frequent a farm in England that got their water from a spring, it wasn't crystal clear, it looked kinda manky actually, but goddamn that was some good tea.
@@memitim171 well, bacteria-infested water is generally okay for making tea. As long as the water stays at boiling temperature for a suitable length of time, the bacteria will no longer be a concern.
When I was a kid I would drink out of the creek if I was thirsty, I’m 74 & still going strong
I was not expecting the comments of this video to be full of people admitting to still drinking very gross water, and not believe in handwashing. This is weird
I was once so desperate for water that i drank alot of water from a small water hole, i could see bugs swimming in my container.
Good question 😊 I've drank from seemingly pristine mountain streams and got deathly ill. I think there is more to the story, such as stomach acidity. I do not agree that immunity is the only answer.
The only thing that's weird is that humans did live in "the wild" not long ago and, in fact, still do in some places. So I'm confused about how we didn't also evolve to be more resilient to water illnesses.
We did, and then people that got sick immediately died. Never passing on the inferior genes. But once we got clean water for hundreds of generations after mutations form and sort of scramble the immunity that we once had. And since we aren't drinking bad water anymore there's no way to filter out those bad mutations.
And after enough generations those mutations build up and put us back to square one.
well, we did, kinda of. evolution works in both directions, so as our immune systems get better at detecting and destroying the various microbes in the water, the microbes get better at evading our detection, and better at using the resources within our bodies.
since human and most other animals live much longer than most microbes do, the organisms that get us sick have many, *many* more generations across which evolution takes place. so say for every 1 average mouse lifetime, there's been 100,000 generations of amoeba that have lived, died, and sometimes changed slightly.
really the whole thing is just an arms-race between big animals and tiny microbes where the animals are outpaced by a few orders of magnitude
@@Stikstaour water has not been potabilized for "hundred of generations". And, as the video explains, adaptive antibody resistance is built over an organism's lifetime, with repeated exposure. It's not genetic.
you rely WAY too much on the meme of muh "multiple generational adaptation theory". That barely accounts for half the things explainable today and is usually used as a "give all" answer. If what you say is true then why hasn't our gallbladders or appendixes been completely removed from our system? Obviously we do not eat the same things as our monkey ancestors ate so why do we still have it? Muh "multiple generations theory" holds exactly ZERO water (pun intended).@@Stiksta
@@santiagoacosta777 building immunity is still relative to ones genes. We all build our immunity to different strengths and some individuals cant build one even with a healthy life style and consistant exposure to germs. This Basic principle is better explained in a micro biology class. But Humans are becoming weaker in general due to our advance society. Another example would be our mouths becoming smaller thus having the issue of removing teeth/crooked teeth. Our food is too soft, and refined so we are now haveing dental issues and weaker jaws.

@@missd411 I'm not sure, but I've been to poorer and wealthier localities in Haiti, and none that i visited had running water that was treated (filtration and/or chlorination). Very common, though, to see places selling RO treated water in plastic containers.
I grew up drinking out of small ponds and streams, me and my tapeworms have been fine.
In Shona culture of Zimbabwe it was a practice that when a baby was born to give him water from the local RIVER not well as soon as possible and then as she got older have them lick or put the sand from the village compound and chew the leaves
It was our way to expose them very early to local pathogens and when you visited a new area you first had to drink the local water
That way we had iron strong immunities
Except diarrhea and vomiting in babies can be so much more drastic because babies have a low surface to volume and can't afford to lose water that quickly. Biggest killer of babies in the world, seems like a big risk but the Shona have been doing it a long time i'll bet.
Hope this channel grows because they put out some pretty educational stuff

It's obvious that their bodies hava adapted to the microbes within the stagnant water over time.
I have always been jealous of animals that can eat & drink almost anything: My local crows for example - feasting on week-old road kill and then taking a sip from a contaminated mud-hole.
When I was a rurally-raised kid, giardia ("beaver fever," a parasitic infection linked to infected drinking water) was considered normal part of childhood - like chicken pox or teething pains. Indeed, it was thought best to "get it out of the way" while the child is still in diapers. This wasn't just because of the associated diarrhea, but also because of a widespread folk belief that, once one had giardia, one has it for life. It was thought that, after a couple weeks of discomfort, the body adapted to the microbes, which stayed with the host from then on - a fortunate thing, since one was likely to ingest more of them whenever drinking from a natural source in beaver country.
In true fact, the protozoa that cause giardia only live part of their life cycle in a human host. They mature in the body and replicate there, but the young are pooped out and the mature protozoa die off. However, it's an observable fact that people who have had giardia and "gotten used to it" are rarely troubled by the tummy-discomfort and other symptoms afterward. Antibodies and immunity are something we generally associate with viruses, but it seems like there must be some sort of acclimation to giardia.
Of course, there is also emerging evidence that giardia infections may be a factor in arthritis, Crohn's disease and a few other maladies - but the jury is out on the full story about this, and whether it matters whether a person has been infected once or many times through their life.
Buddy I am from Haiti and in a poor community in my childhood, now I live in Dominican Republic I used to drink dirty water from the river everyday so human adapt too. in DR I drink water from faucet once in a while to keep my immunity.
I came across instructions for making a device to filter water from a plastic bottle with layers of charcoal and sand.. I think you're supposed to boil it before drinking it tho. It's supposed to work even for "pond water". Personally I wouldn't try it near the chemical plant.
Yep, pfoas are everywhere but especially in cities and industrial areas. There's a lawsuit I've heard from

Also, wild animals don't live all that long. Their lives are brutal and short. Parasites limits their lifespans hugely. A cat can live 15 or more years domestically.... in the wild they very rarely get past 7 years.
tinkertailor...This is not quite true; many wild animals have very long lives in the wild. You have been watching too many wildlife documentaries.
@@prettynoose888 Every wild animal lives longer sometimes twice as long on avarage in captivity. I am not saying that keeping them in captivity for no reason is good, but they do live alot longer there.

@@prettynoose888 well there are exceptions afcourse, elephants and hippos i would imagine aswell, since noone is stupid enough to try them.

There's a reason why we de-worm our cattle at least once a year, even though the water they drink is clean. If one of our cows get's sick, we treat them appropriately. If a wild animal get's too sick, it dies. Because we are caretakers, we can extend the life and comfort of our livestock when it comes to sickness such as that from water sometimes.
Contaminated water in the wilderness is a relatively new development. I was born in 1966 and was an avid hiker and backpacker. We went hiking nearly every weekend with friends and in boy scouts and none of us had ever even heard of a backpacking water filter. None of us ever got sick and we always drank right from the streams and springs. It was about the time I got to high school that we even heard of waterborne illnesses.
The water was no better then than now - people are just more vulnerable.
There have always been pathogens in water.
Nowadays with modern technology, an animal may die upstream and contaminate the water. Back before technology, dead animals near water would float up into the sky and disappear instead of rotting in the water...
Hmmm... Sounds fishy to me.
It's called an immune system for a reason. George Carlin stated it the best
Got to exercise it or lose it.
It's like the Homer Simpson syndrome, he eats taunted food all the time, and has become immune to it. The same with them.
I taunt my food all the time too
To put it simply: when an animal is born and gets exposed the water's bacteria ot either gets sick and dies or its body manages to fight it off and survive... The ones that survive breed and pass on their good immune system to ensure their offspring are safe... Well not ensure just increase the chances that is
And yes they do get sick especially as they get older and their bodies become weaker which is why its very rare to have a long lived wild animal
An animal engaging in an explosive diarrhea attack might suggest that it's sick.
Humans have the same immunity. You’ve heard of Delhi Belly, people from other countries eat or drink in foreign countries and they get very sick, but natives from that region can eat or drink the very same thing and are not affected.
It's a good idea to drink from every filthy puddle that you can to build up your resistance.
If every human did that then the ones that died off are the ones with the weak immune system and natural selection will happpen

I wonder if anybody did research on kids vs adults. I mean, who hasn't seen a kid drink from a pddule?
I had friends who had an old cistern at their house. They had gotten municipal water but I guess at one point that was the water source for the home. It collected rainwater runoff into what looked like a concrete hole. Anything could have crawled in there and died. I hope they had some way to filter it back in the day.
You sure it wasn't an old open well? My grandparents had something similar but it was covered.
Only a few hundred years ago man was drinking out those same waterholes. It's all in what you get used to.

However, we've had firecraft for the greater part of a million years. That will really change the biology of a lifeform. We are essentially adapted to using fire to cook our food and boil our water. Tbh, I've got a theory that it's why we think woodsmoke smells wonderful, while any other animal dips out as fast as possible.
@@raspberrybitch4299 Who would drink boiled water? If you're thirsty and miles/kilometers from your home, you gotta drink river/stream water.
They're used to it, but still they live short lives in the wild. You don't see very many sick animals in the wild because they're already dead. As poor as the food is for cats and dogs, they'll still far outlive their feral counterparts. Humans were able to source cleaner water, so they lost much of their resistance to pathogens.
And this ladies and gents is one of the many reasons why we have some many new and weird illnesses and complications.
People are animals as well and adapt to our food/water sources the exact same way. I surely wouldn't go to Mexico and drink the water 😅but I did have a boss involved in the oil field who made trips to Mexico very regularly and he was able to drink their water without getting sick.
Honestly, the same goes when you travel anywhere. I had issues with the water between two US states because the mineral composition was different.

I'm not saying it's on the same scale, just that it's the same basic concept to a different extreme. It's all about what you're acclimated to.

People also can't be outside getting wet & cold as they risk getting pneumonia, but wild animals can. The more you pamper people the less they can handle. The same goes for spelling & grammer & math. Once you let programs do the work you begin to lose the ability to do them without assistance.
Young people can't do any of those three nowadays it seems. Spelling certainly defeats most. Comments sections and forums prove it.😅

Animals actually can get sick when drinking contaminated water from puddles, lakes and rivers as it all comes down to what’s in the water as opposed to how murky is it but those who developed a resistance to the contaminants are likely to survive.
How do you think their immune systems became so good?
I love how this is framed-connectedness to one landscape/biome is such an underappreciated part of life
It's also for the same reason that a human's mouth is dirtier and we have to brush our teeth daily and animals never need to. Most humans are addicted to food and sugar which feed the bacteria and gets out of control. Whereas eating 1-2 meals a day our body would adapt by increasing HGH and we'd need fewer calories per day. We've also taken antibiotics for generations which is reducing our microbiome biodiversity. If only most humans knew about these issues.
I lived in a small town that got water from a small lake, in the spring you could see stuff swimming around in it with the naked eye.
Short answer: Animals are just built different. They're adapted to a life in the wild, while we have adapted to luxuries. Homosapiens and other prehistoric humans were also like this, consuming water from dirty lakes, ponds or rivers.
But of course, I'm no expert or a scientist, please correct me if I'm wrong. I'm just a guy who wants to learn more about animals, both extinct and living. Have a great day.
You're not wrong, but consider you're throwing a die every time you expose yourself to dangerous pathogens. So the safest play is to not expose yourself to them if you can avoid it... Yeah, yeah, I know: "what's considered dangerous?", it's a chicken or the egg conundrum.
Its not really that they're built different, its that their resistance to parasites and pathogens are being constantly tested, and we tend to only see the animals that survive
@@peterahl6807 yes
@@robinator789Also we too have this resistance/resilience but our it not often used and it not as strong as other animals,you can still eat/drink food/water with bacteria and most probably be fine if you are not doing so often but be careful with that.

Another factor is that Americans have generally bad genes for dealing with contaminated water. Over here in Germany, we have springs in the wild where you can drink while hiking. Of course, there are people over here as well who cannot, but most can. We had two Americans come over for a student exchange and both got sick like dogs drinking that water even though for most Germans it is officially considered clean water.
It sounds more like dirty water that people are used to and resilient to the diseases in it. So when a foreigner (those poor Americans) drank it. They got sick. They simply do not have the resilience to the pathogens in that water.
American is a nationality, not a race or ethnicity--there are no "American genes" so that's not really what's happening. If they were white Americans they had European genes, but their immune system was not familiar with the local pathogens of the region
I basically lived outside for years. Drank from puddles, rivers and lakes when it was extremely hot out. Never got sick thankfully. I found a fresh spring coming out of a cliff once. Best water I've ever had.
I have drank water from creeks, mountain springs, lakes , rivers, wells, ponds etc etc and never got stomach problems.. I do sometimes get respiratory problems while drinking water from a new place..
When I was a child my family used an old fashioned hand cranked well with a bucket at the end of a rope. No problems.
The same reason we used to drink out of garden hoses and not get sick.
The same reason we grew up swimming in the duck pond and yes, swallowing the water, and not get sick.
The same reason we played in mud puddles on the streets and not got sick.

And living in a sterile, safe environment isn't conducive to having a healthy immune system.

One of the major contributors to illness in humans caused by water-borne pathogens is human activity. So many of the recorded plagues i recorded history were enabled by humans living in such close proximity and in such big numbers without proper sanitary precautions. People would empty their chamber pots onto the streets every morning, which inevitably ended up contaminating the local water supply. In the wild , well-oxygenated rivers populated with abundant and healthy aquatic flora do a pretty good job of keeping themselves clean, as long as they dont get overwhelmed by pathogens like humans have done in urban settings for centuries. That's basically how chlorine-free swimming pools work.
The biggest contributor to human life expectancy wasn't the eradication of smallpox or any other medical advances, it was our ability to produce and distribute clean and safe drinking water at will.
Humans can actually still drink any water to some degree. The commercial one we use, which is 99% filtered is safe obviously but in places that are not commercialized or far away from civilization, unfiltered water that is 75% to 90% pure can make humans more resilient because the body adapts to it. So which is why people who drinks the filtered their whole life, will definitely feel something from unfiltered ones. While those who adapted, can drink on both types of water.

Germ theory vs. Terrain theory
Is the pathogen making you sick or your body's inability to fight it off?
Both!
It depends on the strain your body is exposed to!
For example there are some pretty harmless salmonellas, but there is also a really aggressive one: just 7 of this tiny guys can make you severely ill!
As a master of confectionery i once took a tiny taste of a raw uncooked cheese cake and got the worst illness of my life: shitting and vomiting for three days on a row! I nearly had to go to a hospital, it was absolutely horrible!

The thing is humans can drink that water too even for years and years, it's just a rare chance for a living being to get a lethal amount of pathogens in their system, a few bacteria wouldn't make it far, but a few thousand would survive and spread.

I used to work with a man who had emigrated to Canada from Mexico. He said that his children could visit the town in Mexico where he was from, drink the water, and not get sick, even though they’d never been there before, while a person from anywhere else would get sick from drinking the water. I asked him if his children were breast fed and he said yes. Mystery solved.
That's pretty common. The local population, like wildlife, become mostly accustomed to the local virus and bacterial flora. At low concentrations there may be no problem, but outsiders, that's a different story. I paid dearly for that reality in the Dominican Republic.

WOW, informative with some poetry at the end. Thank you!
One thing you forgot to mention is that human digestive systems also adapt to the presence of certain bacterial colonies in their area and depend on them to be properly balanced in much the same way that the animals do. Long before purified water became available, there were bacterial contaminants in the water. A typical human digestive tract can contain many different species of bacteria. Some bacterial species are actually beneficial to humans, for instance, there are bacteria that digest milk solids in the gut and have sufficient numbers to convert a normal dietary intake of milk solids into gas or beneficial byproducts that the bacteria release when digesting the milk solids.
Animals definitly have a stronger tolerance for dirty water, but thet are still picky. They will choose cleaner water (compared to dirty sagnant pools for example) if available and they will avoid certain contaminanted waters, even in a drought. They have a pretty good understanding of whats safe for them to drink and whats not.
Hiking in the pyrenees in france i got thirsty and had to drink from a mountainside spring. Delicious and never got sick praise God

The BIG point people miss is that by limiting ourselves to pure water for generations, we are weakening out species immune system - drastically! And we get more extreme every decade.
When I was young and hiking in the Cascades, it was assumed that most drinking water from any long hike would simply be scooped up from any of the numerous streams we would cross, and no one thought twice about drinking from a clear, fast-moving stream.
Paranoia has taken over - and adaptation is busy justifying it....
You were lucky. The "freshest" mountain streams can be loaded with pathogen. Debilitating disease like Giardia pre exist our presence in the "Wild Cascades" and are spread by other wildlife. As long water can flow from a point of contamination to a water body there is a risk. Type 2 errors suck.
The technology that allows us a continuous supply of clean water is a double-edged sword, it's great when it works but being so dependent on it has one major drawback.
