The field of humancryopreservation is lagging behind ... I work in plant cryopreservation and we are able to cryopreserve 1mm³ sized shoot meristem AND plant these plantlets in the field afterwards. Cryopreservation of plant tissue is an important part of gene banking and storing diversity.
@@justanotherloki5569 it all depends a bit, when developing protocols we store them for at least 30 min, as the material should not change anymore once cooled. I helped develop such a protocol for sweet potato shoots and there we saw some differences between some of our varieties we had 2 where more than 90 % of the material we cryopreserved was able to regenerate into a normal plant and 1 where only 10 % did that. Luckily most of the ones we store have a regeneration rate of more than 50%. These % are species and cultivar dependent. But because we work with clonal material and back ups if some of them die it's not a problem. Other people from my lab are also validating long term storage where they regenerate banana plantlets that have been stored for multiple years. Meanwhile we store hundreds banana accessions which had successfull trials.
However in human cryopreservation, the ethical problem is one of the major factors that makes it lag out compared to plants. Also plant cellular structure allows an easier temperature manipulation.

Some thoughts and questions: • Will a person preserved and revived through cryobiology methods have the same qualities, skills, and abilities before his natural death? If physical damage has been done to the body and the mind, by what percentage will they reduce? • If the concept of the 'Atman' is true, what happens to it when the person is in preservation? • Legal consequences: Interim death certificates have to be issued to those who opt for cryogenic preservation which will be scrapped when they're revived. The hospital or the laboratory will contact the family and some government officials to decide if the person should be revived and who will look after him (accommodation, food, etc.); the government may take responsibility for those who don't have family and can contribute to the country's progress. This will help avoid both civil and criminal issues. • Social consequences: Whether or not the person can reproduce after being revived? If yes, will they have normal babies or be physically disabled? • Economic consequences: More competition for jobs.
The last question doesnt make sense. More people wont neccessarily equate to more competition. A greater worker force however is needed to keep up any govnerment. Also, for your first question, no idea. As mentioned in the video, cryobiology cant exactly revive you. But lets say it did, then the amount of damage or changes done to the brain be the biggest factor in what you need to relearn, and it depends entirely on where the damage is, which no one would know.
@@slampestlol, the last point is leveraged against litteraly any new technology "this new wondrous technology has a possiblity to decrease employment for a short time, let's shut it down lads.

Are you aware that you have to be legally dead before they can freeze you? It would be unethical to freeze a living person, so they have to have a doctor pronounce them dead, then freeze them as quick as possible. Then, hypothetically, hundreds of years in the future when we invent magic movie defibrillators that bring people back to life, *_and_* we develop a cure for whatever disease they died from, _then_ they can be brought back.

They got this working very reliably in the 60s using only microwave ovens and conventional refrigeration. It only worked on small mammals though. Tom Scott did a video on it.
I like the method where they take all your blood out replace it with a cold blue fluid and then perform brain surgury that can only be done with no blood flow, then they take out the blue fluid, pump your blood back in, warm you up and your good as new. I think its one of the coolest things out there. Not literally cool though, it cools the body to like 20 degrees, cold for body temperature but pretty nice for room temperature.
Cyberpunk 2077 did a good job explaining why this sucks or SOMA if you are into the less known video games. SOMA is a nightmare of the issues of this. You are not your body, you are not even your brain. The closest thing to actually being you is an electrical loop in your brain. Not THE brain, a loop inside of it. This is important, because when that loop ends by any of many different things, you stop being "You". This has been observed in countless studies, someone was dead a little too long before being resuscitated, part of their brain was removed or damaged, a disease caused atrophy or inflammation in key areas, or even just you aged and certain electrical pathways in your brain opened up or deprecated. Trying to copy that electrical loop, which was created by gradual changes over time to match the circuits created in the brain specifically to accommodate that loop, into a construct, which by design has to have a uniform system of operation is almost bordering on the levels of magical rather than scientific. We're basically talking here that in order for that to be possible, they need to not only have a way to capture the original loop without distorting it, but also create a 1:1 perfect replica of the existing circuit into the circuitry of the machine for every person they do this with. I didn't even go into the higher level stuff how you're not just 1 electrical loop, you're 2 loops that connect to a single completely separate loop while still being their own loops. So they basically need to copy all 3 of your loops AND keep them separated but specifically two of them are able to communicate to the 3rd one or again you become a different person.
well idk we are far away from any computer having the amount of connections a human brains does so right now even if we could get the data we couldnt run your consciousness on anything. Creating these kind of algorithims will be tough as well
If they could preserve the brain, without damaging it, that will be good enough. In theory, a new body could be created (a biologic or mechanical one) to serve as vessel for the brain. Personally, I would go with that option, since it only requires the preservation of a single organ.
@@purple.requiem It will need nourishment ALOT of nourishment. If the brain gets a robotic vessel it can control the brain will still be a biological organ and need food energy to survive.
@@VeryRGOTI at that state the all of the brain activities are halted. So it doesn't need any energy to operate as it's not even operating in the first place
What ted ed is missing is that it doesn't have to be revived. The brain just has to be analysed to be reconstructed. To say that it's proven is right but to say that it can't be done is baseless, it's like claiming an ASI can't exist because it doesn't exist today.
What about harnessing and building on the limitations of natural hibernation to achieve something similar to the stasis sleep of sci-fi movies. It could be useful for things like trips to Mars, where one or two of the crew are awake in 6 month shifts, putting down the previous shift, fine tuning instruments, ensuring the snoozing crew's muscles do not atrophy, other astronaut chores, waking up the next shift. The crew do not age the full 5 years the trip would take thanks to the extremely slowed metabolic rate caused by hibernation. Though before that we'd need to crack the nascent potential of the axolotl in paralell to hibernation to avoid any complications with the human hibernation process if it has any chance of working.
lol in space travel how much time they experience is entirely up to the tech they have driving the ship. Time is relative and the less gravity you experience, the more time passes for you. This is a bad thing, it means you're aging much faster regardless of hibernation stuff. Having literally 0 gravity is the worst situation. If the ship travels at light speed then it's technically worse as this got explained in the book "The Forever War" where just traveling from one planet to another planet fucks up the time for all 3 places to such an extreme that by the time you reach the other planet they have forgotten about you and are probably so much more advanced they will annihilate you effortlessly. In a nutshell, if they have ships like we use now... They will age drastically faster. If they have a ship traveling at light speed... They will drastically slow aging while both planets undergo many, many years of aging. If they travel faster than light... They will go backwards in time. Where they somehow arrive at the destination before they left the previous location. Probably should hope those are only one way trips.
@@setcheck67 Lightspeed? What has that got to do with induced hibernation... You completely missed the point of my comment, and I have no idea where to begin in trying to understand the relevance of your rabbit hole tangent. If you haven't misunderstood the author of this "forever war" you referred to, as you have my comment, the book's author should've conducted further research to prevent misconceptions like yours. Misinformation can be harmful.
There's this show I watch called Manifest. It's about a plane that came back 5 1/2 after it took off. In one episode, you learn that some of the passengers had no one waiting for them when they came back which meant they had no where to go after the plane ride. When you think about it, would cryogenically freezing yourself be worth it if there's no one to greet you when you come out? In fact, there a couple of episodes of Batman TAS which addressed the idea of cryogenically freezing someone with a terminal illness until a cure was found. Our technology might be more advanced now than it was back when the show first came on but we're still no closer to finding a cure for cancer than we are to inventing flying cars.
Technology is growing in a faster and faster rate every year. I’m pretty young right now, so I guarantee we’ll think of something by the time i die. assuming I don’t die young in some horrific accident or something
funny you mention flying cars. we don't have flying cars today because they are loud, take up ridiculous amount of space at both the air and ground infrastructure, and the least unsustainable mode of transport - just like regular cars. The technology isn't the bottleneck. A more apt comparison to cryogenic would be alchemy. You could do it on a very small scale, sure. But good luck doing it to a human body and expecting miracles to happen.
The animals that go into frozen hibernation do so for a short period of time naturally...a human that is frozen for years would have it's organs frozen together....when thawed they would more than likely to be severely damaged..as would joints and bones. Then there's the question of the soul.....love this channel. 🧠
I think it parallels Egyptian mummies to preserve bodies for another life. True, now our methods are 'scientific', and with more equipments, but the motive is similar. Fear of death is a real thing for humanity. Huh history repeats itself. For me, I'd rather RIP when I die than hang on futilely to life.
It's not new information that Tessier is sharing with us cryonicists. Our main concern is whether the damage that occurs during cryopreservation can be reversed, and we firmly believe that it can. We're already aware of the risks associated with cryoprotectants and fracturing, so it's not telling us anything new. As for the idea that there are ethical and social implications that cast doubt on the benefits of cryonics, it's a bit strange and contradictory. We believe that access to potentially life-saving healthcare is a universal human right and everyone should have the opportunity to benefit from it.
I just watched Vsause's Mind Field video called "should I die" and Kurzgesagt's video on how life is made of dead things, and then this shows up in my feed...
Freezing may be simpler than you think, in Iceland there is a frog that is frozen for up to 7 months a year, before freezing the frog boost it's blood sugar over 40 times which stops it's cells from being destroyed while frozen. Sugar is a natural preservative. Freezing may be possible with glucose injections prior to freezing. Should be easy enough to test.
The problem is not just preserving a person or safely unfreezing them but what we can actually do with them when they get out. For a long time I thought that people who were cryogenically frozen, in suspended animation or stasis were essentially in a state of deep sleep. But then I looked into it and it turns out they are all DEAD, stone dead, deceased. Indeed they NEED to be in order to undergo the freezing process. The whole concept of cryogenic preservation depends on idea that it is possible to reanimate a dead body if it's preserved well enough. All these technologies actually do is keep a dead body from degrading. So these frozen people are waiting for a future that not only has a cure for what was killing them but the same technology as Frankenstein. And even then we still face the issue of the machinery breaking down or whether these cryogenic companies will be able to exist long enough keep people on ice.
Well, we can already revive some people that didn't pass 6 minutes of clinical death. We've reached 1 hour for some animals. I think it's safe to bet that in the future there could be such technology. And that's the point. Having a tiny probability is better than nothing. About bankruptcy. Serious companies that fo cryonics are non-profit that have a fund which is invested in low-risk plans. This fund covers for your maintenance and should theoretically cover the transfer of your remainins in case of bankrupcy.
@@BioTheHuman Ok but I don't think those animals or people are really dead. And as I said, you need to be completely dead to be cryogenically frozen. And even if it's non-profit organizations who do this, there's still the question of equipment failures, power outages or local disasters.
@@EccentricGentelman What you think is not what reality is. Yes, those people/animals are dead because their heart/brain stopped functioning and in fact we couldn't do nothing some decades ago when science wasn't advanced enough. "you need to be completely dead to be cryogenically frozen." Yeah and you need to be completely dead in order to be revived in our times too. In fact there are people who have "Do not resuscitate" policy (a legal document) which prevent doctors from applying our knowledge of reviving, and in fact they remain dead, so how can you "they're not actually dead"?. "And even if it's non-profit organizations who do this, there's still the question of equipment failures, power outages or local disasters." I would be dead anyway, so why should this matter to me?
In response to the question "Would you be willing to upload your mind?"... That wouldn't be you. It would just be a copy of your mind. Imagine somebody growing a clone of you with all of your thoughts and memories duplicated within the clone. You could still be alive and the clone would be alive, thinking it's actually you. That doesn't mean you would see and experience the things that the clone is seeing. That's basically what it would be like to upload your mind to something. Scientists literally can't explain, definitively, what consciousness is and how it operates. We're literally swinging in the dark when it comes to preserving our consciousness outside of our bodies.
I seem to be alone in this, but the idea of a perfect clone replacing me does not sound frightening. If it happened instantenous without me or the clone knowing then what would have changed? Nothing really. One could argue that this truly happens irl too. The atoms of our bodies are constantly replaced by atoms from our environment, get literally replaced by identical clones. We don't notice it, so there's no harm done to anyone.
I mean that's sad, but still, why should it matter for your life? We experience death of loved ones in our lifetime too, so what's the difference. You accept it and continue to live.
there’s a book by Stanisław Lem called „Fiasko” and its main character is essentially a man who was released from cryopreservation hundreds of years in the future, has no memory of his past life and neither the characters, nor the readers learn who he is. while it’s not a main theme of the novel, it’s still a wonderful read and i reccomend it whole heartedly
I'm living proof that it is possible with the right being. One must posses the complete faith and ability to survive. In the army I spent 6 weeks in jungle school and lost my canteen and water and twice during that time found water. I consumed over 4 gallons and then after getting to the barracks mess Hal drank 24 glasses of milk. Being dehydrated may be the key. In the winter I had no heat and drank some ice cold juice that put me to sleep as if in hibernation with my vital signs greatly reduced. I was talking to a post doc friend from Russia about it and he thought it could be a valuable measure for people to survive who crash land in remote ice capped mountains. I think I could be the first to come back.
If they can only vitrify small pieces at once, then they must disassemble you into a thousand pieces, vitrify then unvitrify them and reassemble successfully. Solved.

@@DarkKnightBatman420 They do say that sufficiently advanced technology is indistinguishable from magic but who’s to say human civilization will ever reach that point before inevitably driving itself into an evolutionary corner? Still, however refined any technology is, you’d inevitably encounter Theseus’ paradox in which it becomes unclear whether there can be any continuity of identity with all the modifications being done. But who knows? Maybe then someone’ll also have grasped the construct of the soul or revealed it for the simple biology it is.
Have you seen Altered Carbon? The notion of soul will probably be replaced by identity in the future when we can copy minds and load them into blank humans for war purposes or work.
@@DarkKnightBatman420 The thing is all imagination is starkly limited by present biases. Just like how most people just a few decades ago couldn’t have ever imagined that we’d carry devices with the processing power of the super-computers of that time with us every day; just as much is our current imagination of what could be limited by current (mis)information. As such, there’re endless possibilities of what a “soul” might be or even grounds to invalidate the entire argument; just like how most would frown upon “medical” practice of just several hundred years ago; so could future generations look upon any discussion of identity and self.

Well, stating the problem like that is like saying "I can't eat this burrito because the peas are frozen" while ignoring that the entire burrito is made out of expired food. The problem isn't just damaging small cells. Let's say that no cell was "damaged" by ice formation in this ideal world. Water does not freeze at a 1:1 volume ratio. Frozen water becomes more compact, meaning that all of the water in the human body would, instead of being evenly distributed, be in clumps all over the body. It also means that water that used to be inside of cells gets out of the cells and joins various clumps of ice. Once someone is frozen like that, they are instantly dead, because there is no way to thaw them in such a way that all of the water returns to where it used to be, meaning that trying to thaw the person will end up melting them entirely, as the cells all lack water and will simply fall off. Most of the body would be liquefied and fall off. As for uploading my mind - no, not as such. There would be no continuity of consciousness, meaning I'd just be copying my mind and creating an AI with my memories and thought pattern. I'd still die off. That might be an acceptable thing to someone who's extremely smart, but my mind isn't worth copying just to have my random thoughts live on in eternity, and it wouldn't mean I live forever. Might as well just write a book if all that's left of me is a memory of who i was. If we ever develop technology to a point where we can store our actual brains and connect them into a virtual space and live entirely in a fictional world, yeah, sure. Then I'd live forever, or however long I feel like, and I wouldn't be creating another lifeform with my memories in some weird aberration of science.
The problem is that soul needs a functioning body to reside in. If you stop the body from functioning, the soul will just leave. Then when you thaw the body it will be useless because its soul has already left.
in the future when we are able to settle the debate of if consciousness can be made if you have a big enough brain or if it's like a spirit that merely inhabits the human body will be interesting
You’d need to figure out how to flash-freeze every part of the human body at the same time (flash-freezing prevents ice crystals from destroying frozen food.)
What about the effects on the brain and cognition? Even if they overcome all of the hurdles of freezing and thawing without causing any _structural_ damage, what cognitive state would you be in when you were thawed out after being frozen for years/decades?
Even if the chances to be revived are very tiny, they're still higher than zero (aka dead and not frozen). If you have the money, I really don't see why you shouldn't try.
Honestly, we're probably gonna get there in at most 50 years, technology is getting more and more advanced by the day and it's only getting faster. One day maybe we'll be able to abandon our weak flesh for the strength and certainty of steel
Sure it is. Every time you seek medical attention you’re trying to push back against death. Every time you breath, eat or drink you’re pushing your life forward against death. Everyone, everything, we consider living is solving the problem of death second by second. Modern medicine is just taking the solving to a way higher level.
I don't feel like dying if I don't have to. Skip the freezing and reanimation, and go straight to immortality with nanomachines, and now you're cooking!
Wait, instead of looking for ways to preserve our entire body, why not just find a way to safely remove the brain, and preserve that instead? I mean, that is still gonna be hard, but much easier than preserving an entire body, right?
Pretty sure there's a company that does that already- where they preserve just the head severed from the entire body. Somewhat gruesome if you ask me. There's also this thing with mind-uploading that might be a more feasible goal to preserving someone's consciousness.
@@koshka02Uploading is more feasible and absolutely will be a thing. The issue is that that's not the original person. Someone would be dying so their... Other self can continue on and their loved ones will have them, but not actually them (and who knows whether that's really a comfort). All the while, the original will die and not experience any of it.
@@ElusiveTy that's correct. In the case of uploading, that would be a duplicate, not the original. Unless we figure out how to transfer the actual consciousness of a person?
The physical is temporary, the spiritual is forever.Through Jesus anyone can live forever - with a new body that will never die nor get sick. Those things are the result of sin in the world.

I can’t believe it will become possible. If we could do such things ,the ecosystem of human being and other animals would be destroyed. I can’t believe this at the same time I don’t want that things become possible.
What there is to lose, though? You are going to die anyways and there is no way to escape it, for now. Maybe by freezing myself I die anyways but what if I could be revived afterwards? If there is nothing after death and I can't take my money with me I don't see any reason to not try, in the worst case you get the same result as doing nothing.

Some thoughts and questions:
• Will a person preserved and revived through cryobiology methods have the same qualities, skills, and abilities before his natural death? If physical damage has been done to the body and the mind, by what percentage will they reduce?
• If the concept of the 'Atman' is true, what happens to it when the person is in preservation?
• Legal consequences: Interim death certificates have to be issued to those who opt for cryogenic preservation which will be scrapped when they're revived. The hospital or the laboratory will contact the family and some government officials to decide if the person should be revived and who will look after him (accommodation, food, etc.); the government may take responsibility for those who don't have family and can contribute to the country's progress. This will help avoid both civil and criminal issues.
• Social consequences: Whether or not the person can reproduce after being revived? If yes, will they have normal babies or be physically disabled?
• Economic consequences: More competition for jobs.
The last question doesnt make sense. More people wont neccessarily equate to more competition. A greater worker force however is needed to keep up any govnerment.
Also, for your first question, no idea. As mentioned in the video, cryobiology cant exactly revive you. But lets say it did, then the amount of damage or changes done to the brain be the biggest factor in what you need to relearn, and it depends entirely on where the damage is, which no one would know.
@@slampestlol, the last point is leveraged against litteraly any new technology "this new wondrous technology has a possiblity to decrease employment for a short time, let's shut it down lads. And while we are at it let's throw out the steam engine, electricity, printing press, automobiles, etc. And go back to serfdom where there was 100% employment 100% of the time"
Are you aware that you have to be legally dead before they can freeze you? It would be unethical to freeze a living person, so they have to have a doctor pronounce them dead, then freeze them as quick as possible. Then, hypothetically, hundreds of years in the future when we invent magic movie defibrillators that bring people back to life, *_and_* we develop a cure for whatever disease they died from, _then_ they can be brought back.

They got this working very reliably in the 60s using only microwave ovens and conventional refrigeration. It only worked on small mammals though. Tom Scott did a video on it.
Except the point he made on that is it doesn't scale up. You can't properly preserve or thaw a person as quickly as a small gerbil

I like the method where they take all your blood out replace it with a cold blue fluid and then perform brain surgury that can only be done with no blood flow, then they take out the blue fluid, pump your blood back in, warm you up and your good as new. I think its one of the coolest things out there. Not literally cool though, it cools the body to like 20 degrees, cold for body temperature but pretty nice for room temperature.

I love that idea! I can annoy my besties even after my death.
That would just be your data ran by algorithm. It won't copy your consciousness.
Cyberpunk 2077 did a good job explaining why this sucks or SOMA if you are into the less known video games. SOMA is a nightmare of the issues of this. You are not your body, you are not even your brain. The closest thing to actually being you is an electrical loop in your brain. Not THE brain, a loop inside of it. This is important, because when that loop ends by any of many different things, you stop being "You". This has been observed in countless studies, someone was dead a little too long before being resuscitated, part of their brain was removed or damaged, a disease caused atrophy or inflammation in key areas, or even just you aged and certain electrical pathways in your brain opened up or deprecated.
Trying to copy that electrical loop, which was created by gradual changes over time to match the circuits created in the brain specifically to accommodate that loop, into a construct, which by design has to have a uniform system of operation is almost bordering on the levels of magical rather than scientific. We're basically talking here that in order for that to be possible, they need to not only have a way to capture the original loop without distorting it, but also create a 1:1 perfect replica of the existing circuit into the circuitry of the machine for every person they do this with. I didn't even go into the higher level stuff how you're not just 1 electrical loop, you're 2 loops that connect to a single completely separate loop while still being their own loops. So they basically need to copy all 3 of your loops AND keep them separated but specifically two of them are able to communicate to the 3rd one or again you become a different person.
well idk we are far away from any computer having the amount of connections a human brains does so right now even if we could get the data we couldnt run your consciousness on anything. Creating these kind of algorithims will be tough as well
Like Vanilla Sky?
If they could preserve the brain, without damaging it, that will be good enough. In theory, a new body could be created (a biologic or mechanical one) to serve as vessel for the brain. Personally, I would go with that option, since it only requires the preservation of a single organ.
Do you have any idea how complex the brain is? There are thousands of connections that have to be made properly
how would the brain get nourishment?
@@VeryRGOTI it doesn't need
@@purple.requiem It will need nourishment ALOT of nourishment. If the brain gets a robotic vessel it can control the brain will still be a biological organ and need food energy to survive.

What ted ed is missing is that it doesn't have to be revived. The brain just has to be analysed to be reconstructed.

So it works perfectly. Thanks Ted Ed!
Seeee these videos ask such good questions. Like questions I didn't even know I had and then I need to watch them
What about harnessing and building on the limitations of natural hibernation to achieve something similar to the stasis sleep of sci-fi movies. It could be useful for things like trips to Mars, where one or two of the crew are awake in 6 month shifts, putting down the previous shift, fine tuning instruments, ensuring the snoozing crew's muscles do not atrophy, other astronaut chores, waking up the next shift. The crew do not age the full 5 years the trip would take thanks to the extremely slowed metabolic rate caused by hibernation. Though before that we'd need to crack the nascent potential of the axolotl in paralell to hibernation to avoid any complications with the human hibernation process if it has any chance of working.
lol in space travel how much time they experience is entirely up to the tech they have driving the ship. Time is relative and the less gravity you experience, the more time passes for you. This is a bad thing, it means you're aging much faster regardless of hibernation stuff. Having literally 0 gravity is the worst situation. If the ship travels at light speed then it's technically worse as this got explained in the book "The Forever War" where just traveling from one planet to another planet fucks up the time for all 3 places to such an extreme that by the time you reach the other planet they have forgotten about you and are probably so much more advanced they will annihilate you effortlessly.
In a nutshell, if they have ships like we use now... They will age drastically faster.
If they have a ship traveling at light speed... They will drastically slow aging while both planets undergo many, many years of aging.
If they travel faster than light... They will go backwards in time. Where they somehow arrive at the destination before they left the previous location. Probably should hope those are only one way trips.
@@setcheck67 Lightspeed? What has that got to do with induced hibernation... You completely missed the point of my comment, and I have no idea where to begin in trying to understand the relevance of your rabbit hole tangent. If you haven't misunderstood the author of this "forever war" you referred to, as you have my comment, the book's author should've conducted further research to prevent misconceptions like yours. Misinformation can be harmful.

There's this show I watch called Manifest. It's about a plane that came back 5 1/2 after it took off. In one episode, you learn that some of the passengers had no one waiting for them when they came back which meant they had no where to go after the plane ride. When you think about it, would cryogenically freezing yourself be worth it if there's no one to greet you when you come out? In fact, there a couple of episodes of Batman TAS which addressed the idea of cryogenically freezing someone with a terminal illness until a cure was found. Our technology might be more advanced now than it was back when the show first came on but we're still no closer to finding a cure for cancer than we are to inventing flying cars.
I literally watched the Batman episode today where Freeze tries to preserve his wife 😂
Technology is growing in a faster and faster rate every year. I’m pretty young right now, so I guarantee we’ll think of something by the time i die. assuming I don’t die young in some horrific accident or something
funny you mention flying cars. we don't have flying cars today because they are loud, take up ridiculous amount of space at both the air and ground infrastructure, and the least unsustainable mode of transport - just like regular cars. The technology isn't the bottleneck.
A more apt comparison to cryogenic would be alchemy. You could do it on a very small scale, sure. But good luck doing it to a human body and expecting miracles to happen.

It's not new information that Tessier is sharing with us cryonicists. Our main concern is whether the damage that occurs during cryopreservation can be reversed, and we firmly believe that it can. We're already aware of the risks associated with cryoprotectants and fracturing, so it's not telling us anything new. As for the idea that there are ethical and social implications that cast doubt on the benefits of cryonics, it's a bit strange and contradictory. We believe that access to potentially life-saving healthcare is a universal human right and everyone should have the opportunity to benefit from it.
I just watched Vsause's Mind Field video called "should I die" and Kurzgesagt's video on how life is made of dead things, and then this shows up in my feed...
Freezing may be simpler than you think, in Iceland there is a frog that is frozen for up to 7 months a year, before freezing the frog boost it's blood sugar over 40 times which stops it's cells from being destroyed while frozen. Sugar is a natural preservative. Freezing may be possible with glucose injections prior to freezing. Should be easy enough to test.
Why would anyone wanna cheat death if you get to go to heaven and live forever.

Same.
Discovering cryionics actually gave me vitality.
It's not that expensive and the possible winning is enourmous.
The problem is not just preserving a person or safely unfreezing them but what we can actually do with them when they get out.
For a long time I thought that people who were cryogenically frozen, in suspended animation or stasis were essentially in a state of deep sleep. But then I looked into it and it turns out they are all DEAD, stone dead, deceased. Indeed they NEED to be in order to undergo the freezing process.
The whole concept of cryogenic preservation depends on idea that it is possible to reanimate a dead body if it's preserved well enough. All these technologies actually do is keep a dead body from degrading. So these frozen people are waiting for a future that not only has a cure for what was killing them but the same technology as Frankenstein.
And even then we still face the issue of the machinery breaking down or whether these cryogenic companies will be able to exist long enough keep people on ice.
Well, we can already revive some people that didn't pass 6 minutes of clinical death.
We've reached 1 hour for some animals.
I think it's safe to bet that in the future there could be such technology.
And that's the point.
Having a tiny probability is better than nothing.
About bankruptcy. Serious companies that fo cryonics are non-profit that have a fund which is invested in low-risk plans.
This fund covers for your maintenance and should theoretically cover the transfer of your remainins in case of bankrupcy.
@@BioTheHuman Ok but I don't think those animals or people are really dead.
And as I said, you need to be completely dead to be cryogenically frozen.
And even if it's non-profit organizations who do this, there's still the question of equipment failures, power outages or local disasters.
@@EccentricGentelman What you think is not what reality is.
Yes, those people/animals are dead because their heart/brain stopped functioning and in fact we couldn't do nothing some decades ago when science wasn't advanced enough.
"you need to be completely dead to be cryogenically frozen." Yeah and you need to be completely dead in order to be revived in our times too. In fact there are people who have "Do not resuscitate" policy (a legal document) which prevent doctors from applying our knowledge of reviving, and in fact they remain dead, so how can you "they're not actually dead"?.
"And even if it's non-profit organizations who do this, there's still the question of equipment failures, power outages or local disasters."
I would be dead anyway, so why should this matter to me?

In response to the question "Would you be willing to upload your mind?"... That wouldn't be you. It would just be a copy of your mind. Imagine somebody growing a clone of you with all of your thoughts and memories duplicated within the clone. You could still be alive and the clone would be alive, thinking it's actually you. That doesn't mean you would see and experience the things that the clone is seeing. That's basically what it would be like to upload your mind to something. Scientists literally can't explain, definitively, what consciousness is and how it operates. We're literally swinging in the dark when it comes to preserving our consciousness outside of our bodies.
I seem to be alone in this, but the idea of a perfect clone replacing me does not sound frightening. If it happened instantenous without me or the clone knowing then what would have changed? Nothing really.
One could argue that this truly happens irl too. The atoms of our bodies are constantly replaced by atoms from our environment, get literally replaced by identical clones. We don't notice it, so there's no harm done to anyone.
Yes. That would be photocopy of the original and not the original itself.
In the Quran, God promises, “Every soul will taste death. Then to Us will you be returned” (29:57).
If you were able to come back in the future,everyone you ever known will be gone,so that's something to think about.
Not a problem for me, I don't like anyone I've ever known.
Not if they are cryopreserved too.
That happens to people any way when they live long enough.
Why would I be the only person to come back?
I mean that's sad, but still, why should it matter for your life?
We experience death of loved ones in our lifetime too, so what's the difference.
You accept it and continue to live.
there’s a book by Stanisław Lem called „Fiasko” and its main character is essentially a man who was released from cryopreservation hundreds of years in the future, has no memory of his past life and neither the characters, nor the readers learn who he is. while it’s not a main theme of the novel, it’s still a wonderful read and i reccomend it whole heartedly
We can freeze the body, but... then it's over.
I'm living proof that it is possible with the right being. One must posses the complete faith and ability to survive. In the army I spent 6 weeks in jungle school and lost my canteen and water and twice during that time found water. I consumed over 4 gallons and then after getting to the barracks mess Hal drank 24 glasses of milk. Being dehydrated may be the key. In the winter I had no heat and drank some ice cold juice that put me to sleep as if in hibernation with my vital signs greatly reduced. I was talking to a post doc friend from Russia about it and he thought it could be a valuable measure for people to survive who crash land in remote ice capped mountains. I think I could be the first to come back.

Still, however refined any technology is, you’d inevitably encounter Theseus’ paradox in which it becomes unclear whether there can be any continuity of identity with all the modifications being done. But who knows? Maybe then someone’ll also have grasped the construct of the soul or revealed it for the simple biology it is.
Have you seen Altered Carbon? The notion of soul will probably be replaced by identity in the future when we can copy minds and load them into blank humans for war purposes or work.
@@DarkKnightBatman420 The thing is all imagination is starkly limited by present biases. Just like how most people just a few decades ago couldn’t have ever imagined that we’d carry devices with the processing power of the super-computers of that time with us every day; just as much is our current imagination of what could be limited by current (mis)information.
As such, there’re endless possibilities of what a “soul” might be or even grounds to invalidate the entire argument; just like how most would frown upon “medical” practice of just several hundred years ago; so could future generations look upon any discussion of identity and self.

It's *impossible* that I'm not living forever
Well, stating the problem like that is like saying "I can't eat this burrito because the peas are frozen" while ignoring that the entire burrito is made out of expired food.
The problem isn't just damaging small cells. Let's say that no cell was "damaged" by ice formation in this ideal world.
Water does not freeze at a 1:1 volume ratio. Frozen water becomes more compact, meaning that all of the water in the human body would, instead of being evenly distributed, be in clumps all over the body. It also means that water that used to be inside of cells gets out of the cells and joins various clumps of ice. Once someone is frozen like that, they are instantly dead, because there is no way to thaw them in such a way that all of the water returns to where it used to be, meaning that trying to thaw the person will end up melting them entirely, as the cells all lack water and will simply fall off. Most of the body would be liquefied and fall off.
As for uploading my mind - no, not as such. There would be no continuity of consciousness, meaning I'd just be copying my mind and creating an AI with my memories and thought pattern. I'd still die off. That might be an acceptable thing to someone who's extremely smart, but my mind isn't worth copying just to have my random thoughts live on in eternity, and it wouldn't mean I live forever. Might as well just write a book if all that's left of me is a memory of who i was. If we ever develop technology to a point where we can store our actual brains and connect them into a virtual space and live entirely in a fictional world, yeah, sure. Then I'd live forever, or however long I feel like, and I wouldn't be creating another lifeform with my memories in some weird aberration of science.
The problem is that soul needs a functioning body to reside in. If you stop the body from functioning, the soul will just leave. Then when you thaw the body it will be useless because its soul has already left.

The issue is seeing death as a problem to solve, when it's not.
Sure it is. Every time you seek medical attention you’re trying to push back against death. Every time you breath, eat or drink you’re pushing your life forward against death. Everyone, everything, we consider living is solving the problem of death second by second. Modern medicine is just taking the solving to a way higher level.

Wait, instead of looking for ways to preserve our entire body, why not just find a way to safely remove the brain, and preserve that instead? I mean, that is still gonna be hard, but much easier than preserving an entire body, right?
This is already a thing, check out Vsauce’s MindField episode “Should I Die?”
Which poses another question; if you preserve a brain, how are you going to make that person able to interact with reality again?
Pretty sure there's a company that does that already- where they preserve just the head severed from the entire body.
Somewhat gruesome if you ask me.
There's also this thing with mind-uploading that might be a more feasible goal to preserving someone's consciousness.
@@koshka02Uploading is more feasible and absolutely will be a thing. The issue is that that's not the original person. Someone would be dying so their... Other self can continue on and their loved ones will have them, but not actually them (and who knows whether that's really a comfort). All the while, the original will die and not experience any of it.
@@ElusiveTy that's correct. In the case of uploading, that would be a duplicate, not the original.
Unless we figure out how to transfer the actual consciousness of a person?
The physical is temporary, the spiritual is forever.Through Jesus anyone can live forever - with a new body that will never die nor get sick. Those things are the result of sin in the world. Jesus died and rose again from the dead to set us free from sin so all who believe on Him and follow Him can live forever in Heaven - a place that is very real, along with the new Earth where only righteousness will dwell.

What there is to lose, though? You are going to die anyways and there is no way to escape it, for now. Maybe by freezing myself I die anyways but what if I could be revived afterwards? If there is nothing after death and I can't take my money with me I don't see any reason to not try, in the worst case you get the same result as doing nothing.
Definitely. There's nothing to lose.
Me : who randomly cryogeniteclly froze myself
My mom : Wake up!! Time for school
Mr. Axelband's class @ Hastings Middle School in Upper Arlington, OH - Go Bears!
No I don’t want to imprison my soul.
I saw a documentary where a man technically died (heart attack I think) and while the body was still fresh they did something like that where they chilled his body and slowly warmed it back up
It was absolutely nuts, I hope I can find it again because it sounds so fake when I try to explain it
people of 2023: If I freeze myself future humanity will have the technology to unfreeze me and live forever!
1000 years later
??: this is a human mummy, relatively kept in good shape for being 1000 years old
That little red blood cell is so cute! I love it!
Hear me out: taking out the air and THEN freezing the person
I really feel left aside hearing and seeing several testimonies from people on profits they make from Bitcoin/Forex Investment... Can someone recommend a good expert that trade on my behalf and generate profit for me..
Who is this Mrs Letton Deb everyone is talking about and how do i contact her directly?
investment is the tiny line that keeps deferentiating the poor from the rich. Mrs Letton Deb has brought these to our door steps i guesst.
Wow can't believe you guys also know expert Mrs Letton Deb
Trading with her has been the best decision i and my husband has made this year
My only regret is not starting up earlier... I and my husband can't wait to cashout tomorrow and reinvest.
