Taking Charge of Your Health

If you had to choose right now, how long would you want to live? 80 years? 90? 120? Longer? And do you think you’ll change your mind once you reach that age? Fifty thousand years ago most humans died very young. As we learned how to use the resources around us to treat ourselves, this got better and better. Today, humans are living longer and healthier lives than ever before. But this has an unforeseen consequence. We spend an ever-increasing part of our lives being sick and in need of care. Most of us will die in a hospital bed, which is depressing enough by itself. But we also have to witness the same happening to our loved ones. Except, maybe we can stop this forever. The most effective way to treat a disease is to prevent it. It saves many more lives if you stop a million people from smoking, than coming up with better chemotherapies. So why not put a halt to the cause of all disease: the process of aging. In a nutshell, aging is caused by physics, and not biology. Think of cars. Parts wear down from rubbing and grinding. Metal rusts. Filters get plugged. Rubber cracks. Our bodies are worn down by trillions of tiny physical processes. Oxygen, radiation from the sun, our metabolism. Our bodies have many mechanisms to repair this damage, but over time they become less effective. So our bones and muscles weaken. Our skin wrinkles. Our immune system gets weaker. We lose our memory and our senses diminish. There’s no such thing as dying of old age. We all die because one of our important parts breaks. The older we get, the more damaged and fragile we become until one or multiple diseases take over and kill us. Unnoticed by most of us, longevity research has made some unprecedented advances in the last few years. For the first time, we’re starting to understand the mechanisms behind aging and how to manipulate them. Aging is neither mystical nor inevitable, and we might be able to stop or delay it during your lifetime. We’ll discuss the science behind it and how scientists are trying to stop it in another video. But first, if we could, should we end aging? Is this a good idea? The end of aging or life extension makes many people uncomfortable. We’re born, are young, become older, and then we die. This has been the natural order for literally all of human history, and getting old is a good thing, right? We celebrate the idea of living long enough to experience old age. We even call them the golden years. But the reality is that everybody wants to become old, but nobody wants to be old. Think of the Greek myth of Tithonus for example. Tithonus was the lover of the goddess Eos and probably an amazing dude, because she begged Zeus to grant him immortality, so they could spend eternity together. But she forgot to specifically ask for eternal youth. Tithonus was granted eternal life, but he kept aging, unable to die. After a few hundred years, he was reduced to the size of a grape, babbling on senselessly forever. Thousands of years ago, humans already feared never-ending old age. But ending aging does not mean getting weaker and weaker. If you become too old, it’s too late. A 90 year old who stopped aging would die anyway after a few years. Too much damage has been done to his internal machinery. There are already too many surfaces for disease to attack. Instead, the concept of life extension promises to end diseases, and with them, the end of a fixed maximum age. We don’t know how much we could prolong our lives. We might make every human healthy to the currently accepted maximum age of around 120, or we might stop biological aging and disease indefinitely. Nobody knows at this point what’s possible. Okay, but even if we could achieve that, should we? Well, life extension is really just another phrase for medicine. All the doctors are doing is trying to prolong life, and minimize suffering. The vast majority of healthcare resources are spent on the consequences of aging. Nearly half of your lifetime healthcare costs will be spent during your senior years, and another third during middle age. We are actually already trying to prolong life with our current medicine. We’re just doing it very inefficiently. Trying to stop aging from happening is not less natural than transplanting a heart, treating cancer with chemotherapy, using antibiotics or vaccines. Nothing humans do nowadays is purely natural anymore, and we enjoy the highest standard of living ever as a consequence of that. What we’re doing right now is waiting until it’s too late and the machine is failing. And then we use the vast majority of our resources trying to fix it as well as we can, while it breaks down even further. But life extension still feels hubristic. Most people assume that they will want to die once they reach a certain age, and this might still be true. The idea of avoiding death entirely is off-putting for many. The end of biological aging would not be in the end of death in any way. It’s more like a summer evening when you were a kid, and your mom called you inside. You just wanted to keep playing, have a little more fun during sunset before you went to sleep. It’s not about playing outside forever, just a little longer, until we feel tired. If you imagine a world without disease where you and your loved ones could live in good health for another 100 or 200 years, how would this change us? Would we take better care of our planet if we knew we would be around longer? If we could work for 150 years, how much time would we spend figuring out what we’re good at? How much more time would we spend learning? Would the intense feeling of pressure and stress many of us are feeling right now, go away or get worse? So asking again, if you could choose how long to live right now, in good health and with your friends and family, what’s your personal answer? What would you like your future to look like?

  1. I wanna live forever and gonna watch the black hole civilization it's my dream but………
    It can't happen I know 😔😔😔😔😔

  2. 4:30
    "Almost half of your medical expenditure will be spent in your old age and another third in your middle

  3. I want to live 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 or more in my opinion but In real life 70 or 80 or 120 years 😑

  4. It’s impossible to stop aging. Because a child being born will remains a newborn forever. An old man will remains old forever. Then no evolution could happen, everything just stop.

  5. Aging or Genom decay is a fluke in our biology. In fact there are people with a genetic mutation that let's them not age past the age of 30 or so but they all die from the other side effects of that mutation. Namely profound bleeding from the skin.

  6. " Should we end aging forever? "

    I think no
    Disrupting the natural circle of life would almost definetly result in overpopulation and more pollution.

  7. I think human lifespan has very little to do with the human condition, as we still perceive time the same way and our brains still will only plan till the next high, the next reward or the next day. Of course we are widely capable of "delayed gratification". Some of us better than others. But this will not change much with an outlook of 20years, 80 or 200 years of living

  8. Without death, life has no meaning. The fear of leaving this world somedays is what drives people to leave a mark, to be remembered.

  9. The biggest reason why I want to keept living for a few hundred Years is because I want to really see how everything pans out for humanity in the future. Will we be able to colonize other plantes ? Will climate change end us ? There are so many questions that won't be answered in my lifetime….

  10. Not aging seems good on the face of it however. Once you have experienced all major life events there is not much to look forward to. I think most people would become tired of the same thing for years. Other then older people who say I’m ready to go it’s not all about them being old. I feel it’s about they have just had enough saw enough and did enough

  11. Ending aging is a horrible idea. Can you imagine if people live forever. dictators and world leaders who never die would hold onto power forever.

  12. This actually what would happens in the next life in shaa allah ..just imagine, you succeed, and entered the haven…and after that, will live forever in healthy age with the ones you love, :") may allah guide all of us, ameen.

  13. I wonder Can Death be extinct ever?
    May be a time will come when a baby would ask his father : What is Death . And his father would think a lot and say : hmmm ….when our ancestors used to stop living the state was used to be called Death.
    And then the child would wonder : WHAT ARE ANCESTORS REALLY🤔

  14. I hope someone can make a robot and you put your brain in it and you get immortality. What I used to think is couldn't u just get a transplant for a new heart or new lungs but that probably wouldn't work

  15. I feel that if we were biologically immortal we would have more unemployed people more homeless people than ever before

  16. Id love to live longer. Im 13 and know im going to die probably before I hit 40, and if I dont, I dont think id live very long. I work a fair, bit usually get very stressed, and physical wear over several years has caused me back pain, starting to cause joint issues, ive already experianced heartburn, and nearly lost my leg. Ive already lived a whole lifes of memories that im happy with even if I do die young, I maybe have never gotten a girlfriend or will ever have kids, but ill still live life to the fullest with the exception of age. Im already making a business and building structures, when im 18, theres a chance ill become a volunteer infantry soldier and if I live I live after that, ill continue what I do now and more. There will still be a legacy and life left behind when I die, a gap to fill by someone else who will have likely similiar life experiances to me and pursue similiar goals.

  17. I would like to live much longer because of how we seem to get smarter and smarter over time

    Also if we don't have the negatives of aging them we will be able to keep this enormous amount of knowledge and help the world far more than we could ever achieve

    Imagine if Einstein never died and never became old, imagine how much more advanced we could be

  18. А если , в будущем мозг перенести в "металлическое тело" то можно быть бессмертным?

  19. In this current age, I'd like to live until 150+. I look forward to the era where humans are able to travel to space similar to how airlines are a norm nowadays.

  20. i would be fine with being an emotoral, as long as i could have some emotoral friends. and more mental capacity. i love my heath now and i wish to only have it go uphill, becase self preservation is key.

  21. I don’t know honestly. On one hand, it would be comforting knowing that I could literally have all the time in the world to experience life, and when I’m comfortable, death as well. But on the other, isn’t time somewhat the factor that drives us forward? As it is now, we all know we’ll die someday, so we strive to complete things to improve our lives for the future, before your too old to do so. If we were eternally young by choice, why would we choose to have kids? Start a family? Hold a career? Why would you take opportunities if you knew that it isn’t a limited time offer, if you knew that your life is as long as you want, so maybe the offer will rise again. Perhaps an inevitable death is what pushes us to make decisions, because if we don’t, we know we might not get that chance again in our lives.

  22. I want to live for long enough to experience a world free from Terrorism , Racism and obviously the root of all evil "Zionism" !!!

  23. My "to do" list is so huge, I would want to live forever. It would take me 3,000 years just to catch up with my current to do list. During that time, the list would grow larger.

  24. We would quickly become so overpopulated as to make life miserable for everyone and cause such extreme environmental damage to the point of, ironically, mass extinction.

  25. Majority of humans in this planet deserves to die and dont deserve such technology. It should be reserved for select few enlightened individuals only.

  26. Immortality so does the eternal problem so does someone who doesn't want any one become immortality except them

  27. 1st it is not the human body (avatar) which is LIFE. The Real Self or Consciousness is LIFE or the Observer, and is not a component of the brain. The human body gets ill, suffers, and dies, because "Double Logic" is present in the Human Genome. But on other hand The Real Self or LIFE is Eternal.

  28. There are so many interesting things to learn out in the wild and only being able to be educated in one or two fields deep enough to fully grasp the ideas behind them is just sad

  29. Well if we stop ageing that wold be amazing right . Of course you say well if we stop 🛑 age then bdays what happens would they be important and if we “never die” the an we would exhaust our supplies and overpopulation

  30. You know i don't want to live forever just to have fun and play i just want to KNOW i want to know what well happen in the future and how well the humans Die and i want to see what happened before us and what well happen after humans die and after all the stars and black holes die i want to see that 💔

  31. End aging and keep scum like Trump around forever? No thanks. Let the old minds die so that better ideals can take root.
