Some people will want this. Some won’t. I used to volunteer with the elderly for years I will never forget a woman of whom I spent a great deal of time. She was 97 years old. Fit and still of sound mind. She’d take a puff of her cigarette and tell me, “God is cruel. Everyday I wake up is like a cruel laugh to the face. My time on this earth is over. I’ve done everything and I’m ready to go now.” I’m serious everyday I’d see her she wished she were dead because she felt as though her life was complete and there was nothing more for her to do. She’d tell me all these wonderful stories of her life experiences. She’d tell me she lived a fulfilling life. Some people come to a point in their lives in which they feel as though they have lived a fulfilling life and they just want to go. In my own observation those who feel unfulfilled always wish for more time to be fulfilled. Nothing is wrong with either. Just an interesting observation.

I exercise every day at a gym ,walk my dog, and eat a nutritious diet. I think I'm doing everything I can. I would prefer to be healthy now than live for ever. I'm 77

I don't really mind looking old, but the elimination of certain diseases that happens in advanced aging is what makes me hopeful about these kind of stuff.

My grandma is 101. She has Alzheimer’s and my parents who are both 80 take care of her with very little help. My sister and I help when we can but we are both married. It has been hard on the whole family. I hope that there will be a cure for Alzheimer’s within my lifetime.

It's true what he says toward the end of the video about exercise. I have worked out at least three days a week since the age of 21. In 2006, at 49 years of age, I got "carded" not once but twice! I have always believed that regular exercise is the true fountain of youth.

Human obsession with eternal youth never disappears...

I don't see aging as a disease, and with a society as we have, such traitement will cost millions and be available just for the bourgeoise, separating more and more the poor from the rich. It will just be identical to the Love, Death and Robots series/tv show.

Quality of life is more important than length of life

Studies show that exercise increases the length of telomeres.

Ali said it best.... Don't count the days...make the days count....

People don’t want to live longer. They want to look better and feel better.

If I died at the age of 100 , in the appearance of 30, I would follow all they say

I'm really glad BBC decided to give exposure to such an important field.

I like the whole idea of staying young (young soul). Just because you are getting old doesn't mean you have to give up taking of yourself or your appearance leading to a more fulfilling life. But getting older or growing older has always good things too. So taking a good care of yourself + life experience = amazing person.

My grandfather was basically a shell of the man he once was after my grandmother died. He died at 86 of leukemia and honestly I don't think he would've wanted to keep living. That woman was his world.

Yes. It can be stopped. There is no honor for aging. It pains me to see poor elderly stuck in retirement home. I can't let that happen!

Now imagine having a neighbor who was born in 1860... That would literally freak me out.

After watching this, I still want to die fast and painless.

I really appreciate such an incredible efforts

Fasting increases the release of human growth hormone from the pituitary gland which can slow the aging process

*and as i watched this video i aged 30minutes...MAKE IT STOP*

I work in aged care and god, no one should get old, it is utterly 100% hideous on every level!!!!! really is a curse

Age is just a number, and it depends on what we think about ourselves. Age is what you make it, if you think that you are old you already old if you think you are young, congratulation, you are young at heart.

Rich people : reverse aging Poor ones : rather die than suffer consequences !

I would like to warn viewers about anti aging creams. I got some for my birthday last year. I used it every day. Imagine my disappointment when my birthday came around this year and I was exactly one year older - exactly what I would have been had I not used the stuff!

Great job Mary, always a pleasure to listen to Liz and other aging researchers! I think a lot of people will be surprised when some of us hit escape velocity in a few years but we won't realize we have till a few years later!

¨My jewelry is in the inside" Wow, fantastic remark!

Seems they all got little pieces of the puzzle. That was 2018, curious to see an update.

She is so right, to risk her own life and make this sacrifice is a very small price if it can mean the end of so much suffering and death for so many, especially if she feels her thinking is sound and the results significant enough to warrant this risk. Good for you Liz for doing this for the potential benefit of so many, I commend you!

Longevity is the key to solving problems that span many current generations. When people can see themselves in the far future they will care about the long term effects of their actions today.

I glossed over the speech and listened to the music. It is so relaxing. What is the name of the song?

Ask queen Elizabeth, 😂. It is fun to be alive for wealthy people.

Nothing wrong with wanting to live as healthily and as long as possible, but some of these people just seem to fear the inevitable.

I want to meet people like Cynthia and Nathaniel in the near future to help my parents and grandparents and cure their aging problems for good. I love the work these people are doing. Nice informative documentary BBC. I hope I get lucky.

I am very interested in this topic!

You look great Liz!!!! Thank you for such for a lovely program and all the searching and researching!!!! Thanks BBC

4:01 the window cleaners must really hate that woman

The reason chromosomes have telomeres which shorten is to prevent the prolongation of old cells which have acquired DNA damage and hence are at risk of developing tumours. Preventing this process may inhibit ageing but will promote the development of cancer cells.

Every thought that's expressed will definitely get collaborators....that's what keeps life moving!

amazing theme!!! go on

Incredible !! Thanks a lot for this documentary 😍😍

I'm one of those believers. I hate aging.

There are two projects that I would live all behind to be part on, the Sword Art online, Matrix and USS Calister device on the second place, but becoming a non-aging person will be the first one. There is nothing more valueble then time on our existance,It doesn't matter where you are, the most of the people wants more time, so the research will keep going till it will be reached. Every power aspect has the rich/poor duality but I prefer to live on a world with the immortality possibility, and throw myself on a black hole when I become tired to live, and regret possibily this thought during the journey. I already have more to live then my time allows, so why not have illimited time. Travel for the space and create life on anothers planet, it will take some time.

love way she just explains it on a glass window...thought we had whiteboards in this day of age lol

I fully support the mission to get aging under medical control. I want my family, myself, and anyone else who wants it to be free from horrible age related diseases, disabilities and ill health which include: Alzhiemer's disease, other forms of dementia, loss of bone, muscle and lung function as well as weakened immune system. I look forward to a future where people have the ability to decide whether they will grow old and die from it, or stay youlthful.

I’m going to live forever, or die trying.

Amazing and inspiring

I'm sorry for people who can't see the beauty of aging.. since I was little girl I love being around old people.. I have been working with elderly people since 02, and by what I see it give me hope for the future... The Sades think I have seen young disabled people living in Nursing Homes.. That's Sad !

I just wanted healthy ageing.

I think the secret to longevity is simply based on what you eat the levels of stress and toxicity that you are exposed to. Everything in your body regenerates. It only depends on whether or not you give it the appropriate conditions to regenerate properly. The idea of living longer by simply taking a pill will have other consequences in my opinion proper sleep and exercise is very important as well

Terrifying this video, I feel strange after watching this, even I would say frightened about the future.

This's a great show. I'd really love to live longer with young and healthy body and mind. There's also a documentary on this subject by professor Michio Kaku, 'Life time'. Highly recommended!

really appreciable! Great work. Nothing is impossible if we do keep on trying.

i aged watching this

Fantastic reporting!

Mother Nature will always find a way to re-balance over-population!

okay....regardless of how awesome this new technologies are the BEST way to prevent ageing is by removing inflammation foods in the diet AND to fast 16 hours a day.

I am scared of dying but not as scared of not dying .Its comforting that this will be over one day

Do you have a follow-up docu on this, @BBC News?

Even if I didn't beleive in an afterlife ,I would rather choose death than this

In the Sci Fi story "Cities in Flight" the characters were able to explore the stars due to their extended lifespan. It took a combination of therapies to massively extend people's age. To around 800 years. Interesting.

I think aging is somehow beautiful up to some point where you start to develop problems because of that, but aging shows experience, emotions, it shows part of who you are and how has life shaped you some might even have the luck to age and look better than when they were young, more sophisticated even. What is the real beauty in looking 20 all your life besides the outside, if what you have inside is all rotten? Age can bring also sometimes respect from the youngsters, it is something that should not be looked at as horrible, stopping the process at some point may be beneficial for the health but the appearance is not to be considered the whole purpose.

I am 45, and I've lived a full on beautiful life so far, I take every day as Bonus now if I look nice, feel good and stay healthy. Satisfaction is the best version of peace and happiness to me. Nah, not interested in stressing so hard just to look younger! But yes I would like to find a way to die as healthy as possible. 🙊 I hate suffering and feel terrible when especially children suffer before even living a life. 🧡

What did she use in the iv drip? Was it NAD?

How does the anti-aging therapy affect the offspring of the mice? This is a very important question.

this actually makes me sad, seeing old people trying to be young again.

even if you could, how would you implement it to a vast amount of different specialised cells and the new cells that will be born?

If we live forever, life will loss meaning. It’s precious because we only have a short life to live which we want to live healthy and happy. I, for one do not want to live forever.

Talk about a mid life crisis

It is accumulated damage that causes ageing. We can intervene to end ageing and the suffering it causes. Senescent cells and mitochondria cause a lot of damage. We will see therapies emerge, over the next twenty years, targeting the diseases of ageing. Longer lifespans will be a side effect of this intervention.

If we dont die it doesnt give us drive and ambition and appreciation...the nature of death is more important then u think...

its cool to see that the field of longevity is becoming more main stream. of course there are haters but they will also be the first ones in line when longevity treatments come out

I can't think of anything theoretically worse than living forever.

I see this and I think of my great grandmother. She was a wonderful woman and Im greatful that she lived long enough for me to know her. she was almost 100. The sad thing was she out lived her siblings, 4 of her 5 children, 2 grandchildren. she said how awfull it was to out live all her peers

Awesome video. Ty BBC

Why am i seeing this documentary today, its so cool, where was I in the world not to have watched this,😄. I really like the subject in this

I can see why people are afraid of 'living forever', especially when it is involuntary. I don't think anybody is suggesting that we subject all humans to a kind of compulsory treatment that extends our lives indefinitely. Instead, the idea is to develop a treatment to prevent, slow, or reverse ageing, when and if a person wants to. You can choose to die at 100 if you want to, some may want to live longer, some may not. I see the real problem here as 'choice'. Sooner or later, human technology will stumble upon the fountain of youth but this will make people conflicted because now they are forced to decide on the most fundamental and arguably the biggest decision of their existence. Our lives were given to us by our parents, but now we have to decide if we want to take it away. Imagine hating your mother for dying because she didn't 'choose' to live longer. Or, imagine your children hating you for living longer because they won't get your inheritance. In the past, we could blame death on ageing which takes individual choices out of the equation, but in the future, this may change. Personally, I think people should be given a choice to extend their lives or die a natural death. I don't like the notion of 'not thinking about something' just because it is too hard. That's silly, and that's just avoiding reality. These are questions that everybody needs to think about and reflect on because it is what truly gives meaning to our lives. "What am I living for?" "Why do I do this?" "Who will miss me when/if I'm gone?" "Was I such a terrible person that nobody will miss me when I'm gone?" If you think these questions are too hard and therefore you don't want to think about it, then you can choose to let ageing take you. But for those who need more time on this Earth to figure out the mysteries of life, they can choose to extend their lives.

I was born old...now I live my life backwards. Growing young so, basically by the time you reach your 90's you could easily be arrested like a 17year old....

Thanks

update ?

Aging, and ultimately death, is the great equalizer that subjects even the billionaires of the world.

Don't waste time on Metformin! Stop eating sugars and starch.

How about the island of Ikaria in Greece mostly they reached to a hundred years. Their secrets were "no social discriminations they helped each other if they needed .Their healthy food also are the main factors of combating aging.

also they say ppl who meditate have increased the length of their telomeres and i do meditate a lot and im 48 and been told i look 34 but who knows

I'd want to/rather die early instead of living forever in this foresaken damaged and corrupted world my own species made worse.

/Satisfaction of your life shouldn't be measured by the number of years you lived/

Imagine this!!!! we won’t have knee pain at 25 anymore 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

I suggest reading Cicero’s “On Old Age.”

Omg! I’m a scientist and I can say BBC do a great job on this documentary. I love how they tide the story from telomeres, epigenegics,hormone, and c. Elegans together. It is very informative and easy to understand! Thank you!!! ❤️❤️😊

Nathaniel David does look way younger, for someone who is 50 years old. Im sure he has experimented on himself.

I believe much more would be accomplished if people could live without inflammation, the indicator for many illnesses and pain.

I spent my whole life reaching about heath and stopping the aging process

i m 573 years old and i m feeling great.

it's not the years in your life ,it's the quality of those years.

Nice documentary 👍🏻

There has been so much pain and tragedy with our human race for centuries that I would not want to live long enough to witness more pain, cruelty, and destruction done by humanity.

yu can avoid aging: dont smoke dont do drugs drnk in moderation eat healthy move all these things are free

Don't spend your precious time trying to get more time... That just doesn't make any sense. Just accept that everyone is going to die one day. Expending your lifetime is just a temporary solution, humans will never be 100% statisfied; we are a greedy species.

I will try it

The kind of people who want to live forever are the kind of people who really shouldn't.
