Dr Attia, In recent months I discovered your channel while researching the benefits of fasting for longevity. To my delightful surprise I learned that you where from Toronto and my home during my college years. I was not smart enough to be accepted to QueensU so York settled on me. That's was 1973. As dual citizen born in Woodstock Ontario, I am proud to recommend my friends and colleagues to your Drive RUclips Channel and letting them know your a fellow Torontonian. I blame you for my 40 lb weight loss since Nov22. More importantly the lifestyle changes and exercise adaptation that both are now my life. Thank you for sharing your knowledge and the groundbreaking work you and your colleagues provide. I now can get off the floor unassisted.😊
I have so much admiration and respect towards geniuses who make so much effort to simplify complex topics of science and medicine making them accessible to the masses
Absolutely fascinating! (Thank you for introducing me to Weiss. Reminds me of Tesla.) I like the way your mind works, Sid. Can't wait to read your books and ride your wave.
I learnt a lot from this fascinating podcast; thank you so much! It's sad that this is the first time I'm hearing of Samuel Weiss; wish we'd been taught about him at school.
As a medical doctor Obestetrician we learned about Samuel Weiss. Thanks,In British school of medicine we were taught observation is first tool to diagnose diseases and health,

@@kazoz3520 Yeh I realised this a bit too late when I mentioned this to someone in the field and they were like, "Do you mean Semmelweis?"...thank you for putting it in the comment section anyway as I forgot to update the comment with the correct spelling :)
Absolutely fantastic episode, thank you. As a side note, on the topic of why dinosaurs (among many other organisms) got so big in their day, the topic is discussed (with ample references) in Bill Bryson's wonderful book "A Short History of Nearly Everything" (en.wikipedia.org/wiki/A_Short_History_of_Nearly_Everything). Much had to do with higher oxygen concentrations in the Earth's atmosphere that allowed for these extraordinary large lifeforms to exist (six-feet-long centipedes, for example).
i checked out the sample in his audible version and all i can say is that i wish he had done the narration. It would have made it enjoyable as his inherent understanding of what he has written and his tone in reflection would have made a big difference to the audible only community. Peter would you say his book is also for the non medical community, your average lay person?
what a fantastic pod ❤️ now just to decide in what order to start with Shri Mukherjee books, after finishing Peter’s book of course…currently listening to Goggins 👊🏻💯😀🏃🏿
Most writing is about self because this is really what we know in relation to our environment.We are limited in time, space,senses ,and part of whole ecosystem and our bodies are ecosystem so parts represent the whole and the whole is representing the parts.
In the next interview, would love to hear what Sid thinks *HOW* a cell knows what part of the DNA tune to play... and how the brain produces consciousness (1h48m). How does CRISPR compare to silencing gene expression using RNAi/RISC complex? Aubrey de Grey suggests that CRISPR is great at removing short sequences, but isn't well suited for inserting kilobases of genetic information. Is there a technique that DOES support that? Also, what percentage of cells would need to be targeted in a selected tissue, to repair disease? And even if you had 100% coverage, don't you still need another mechanism on top of it in order to express that new dna? Regarding gene-therapy, what prevents the body's immune system from noticing and killing the modified-virus before it's done any work? The Atlantic had a great story, "You May Already Be Immune to CRISPR". BTW, why is the audio/rss-podcast version of the interview, shorter than the video?
Balance exercises are essential to practice so our bodies correct itself automatically because when we trip over within milliseconds the body correct itself subconsciously. 33percent died after falls in old age( taught in general surgery).Essentials are diet, sleep,muscles movements to last to the end.
It's fascinating to learn how our bodies have the ability to correct themselves subconsciously, especially when we trip or stumble. As we age, our risk of falling increases, and falls can be a significant cause of injury and even death. It's alarming to hear that 33% of older adults who fall may die as a result, underscoring the importance of taking proactive steps to maintain our balance and prevent falls from happening in the first place. You're absolutely right that essentials such as a healthy diet, good quality sleep, and regular muscle movements are all crucial components of maintaining our overall health and well-being, especially as we age. Incorporating balance exercises into our daily routine can be a simple yet effective way to promote better balance and prevent falls from happening. Thank you!
Siddhartha Mukherjee the problem we are facing today that WE STILL DONT WHAT IS LIFE ? ITS A MILLION DOLLAR QUESTION. IF WE KNOW WHAT IS LIFE, WE ARE IMMORTAL, NOBODY WILL DIE
Loved this. Thanks you. At 1.30 hours - you guys are discussing the need for synpase. I've been thinking about the need for synapses between neurons and why electrical signals need to be converted to chemical and then back to electrical signals. It's been bothering me for a while, so I have a question for you: Do you think that synapses are what differentiate humans from robots/AI? Without synapses, everything would be purely electrical with no evaluation or assessment, much like the flow of electricity in our homes. Humans, on the other hand, have the ability to interfere in any process or signaling and override it. For example, when we eat our favorite food, we inadvertently override the leptin hormone. Similarly, with strong beliefs, we have the potential to safeguard ourselves or even heal from acute or chronic ailments. So my question is, if the brain were to interfere with our signaling process, could it be at the synapses somewhere in the brain?
There is also a fifth type of cell therapy - the one that controls the ways the cells communicate so that they interpret the dna in another way to achieve homeostasis, without ever changing the genome or epigenome. This is not pseudoscience, not vodoo, this is provable and it has been proved, for now, in animals. Checkout dr Michael Levin's research. I really hope you read this and just consider to check this out.

Fairly interesting discussion on depression-presumably all genetic mental disorders will have genomic targets to explore and ultimately replace with a “healthy” genome. For those that perhaps suffer from an epigenomic expression of depression from lifestyle/environmental choices, it seems so self-centered given the ability to switch those genes off
While it's true that genetic mental disorders may have genomic targets that can be explored and replaced with a "healthy" genome in the future, it's important to remember that mental illness is a complex issue that often involves a combination of genetic, environmental, and lifestyle factors. Regarding epigenomic expression of depression from lifestyle and environmental choices, it's important to acknowledge that while there may be certain environmental factors that contribute to the onset of depression, it's not always a matter of "switching off" certain genes or changing lifestyle choices. Many individuals who suffer from depression or other mental illnesses may not have the resources, support, or ability to make certain lifestyle changes, and it's important to approach mental health with empathy and understanding. Additionally, it's important to consider the potential ethical implications of gene editing and replacement. While it may seem like a simple solution to replace "unhealthy" genes with "healthy" ones, this approach raises questions about autonomy, informed consent, and equity. It's important to ensure that any genomic research or interventions are carried out in a responsible and ethical manner, with consideration for the potential risks and benefits for individuals and society as a whole. In summary, while genomic research and interventions may offer potential solutions for certain mental health conditions in the future, it's important to approach mental health with empathy, understanding, and consideration for the complex interplay of genetic, environmental, and lifestyle factors.
@@AnnTsungMD yes, it's assumed there are environmental factors as well as adjustable psychological factors, although genetic dispositions should be the forefront of ongoing research.

Way too opinionated: Who is Attia to decide on behalf of others what is deserving of CAS9 gene editing? And who are "The Scientists" who are all of one opinion? This is the antithesis of science. To boot, in China you can't get an IVF certificate if you are HIV positive, so this may have had something to with the decisions taken. There are other issues, as CAS9 is not as precise as this interview makes it seem like, but the moralistic pontifications are at least partially uninformed.
@@karlpk3907 yeah, Daniel’s right being a polymath is not as important as having your hair right. Having your hair right is a big sign of personal hygiene.
Did it ever occur to you guys that evolution DID NOT figure this out. That their was an intelligent designer. You guys don't play these mental gymnastics with any other intelligently designed object except the human being. Why is that?
