Faiza : This was an extremely interesting talk.

Maurício Gerhardt : Now we just have to defeat cancer and we'll be immortal. Until then, don't get stressed and meditate.

Choco Peat : A wonderful science talk that engages from start to end with an incredible message!

Adam Mortimer : I’m glad we are back to the classic Ted talks. I find it fascinating that science continually seems to confirm that stress is a leading cause of disease and the power of meditation Is reaffirmed again and again as a powerful tool against stress. I had a doctor that read thousands of scientific journals and he told me that stress is the root of many diseases. She did a great job. She is brilliant. I am so grateful to the amazing women and men of the science community that are working so hard to improve the leangth and quality of human life.

Jamie Kinthaert : 18-minute video Summary: Telomeres keeps you from degrading. Enzyme telomerase keeps telomeres from shortening. So take telomerase? No, because although it reduces some diseases, it can also increase some cancers. The rest of the talk goes on about quality of life, keeping low stress, having a more positive outlook to bad situations, all of which reduce telomere shortening. IMO, I know cancer is no joke, but I am tempted to try it to see how it affects aging.

Mola Diver : About 22 years ago I wrote a paper in school about telomeres. I still remember how they caught my attention back then. It's just incredible to see how people such as yourself decide to devote their lives to this topic. Respectfully, you seem to be a very joyful and positive person by nature so I hope that means your telomeres still allow you to conduct many more years of research. Thank you very much Elizabeth for this incredibly informative and inspiring talk!

lonar30 : She looks very sweet and intelligent woman...

ShePudding : Calling pond scum cute? No. *She* is cute, in a kindly mother kinda way. I kept thinking “It’s okay! Keep going! You’re doing great!” when she stumbles, but she got through it. :) Oh. Also: good info. Very interesting. Cool cool. 😎👍

MrTommy4000 : to paraphrase... don't worry, be happy

Prakhar Awasthi : This is one of the best Ted talk I have ever seen. Wonderful

Natalie Gil : What a great talk, I find it wonderful how people arent actually wasting their time, at least not all of us.

Ch 17 : Fascinating field of study. I like TED talks focused on science and research.

saltydawg : So basically, pond scum are super chilled..

Chris Hart : I still remember going to a lecture in the 9th grade about 25years ago at Purdue University where a good portion of the lecture was about telomeres, aging & cancer. Super interesting then, still interesting now.

Benjamin Fisher : At least i know what Hillary is up to after the Election

Huy Savage : for some reason she reminds me of an owl

bj0rn : Her conclusion is much more general than the rest of her talk. She's basically begging politicians and the public to fund curious researchers who wants to explore the unknown rather than only research where we are able to predict clear applications. The thing about research is that we don't really know where we are going, and unexpected applications often come afterwards, so it may be unwise and perhaps wasteful to only fund easily motivated research.

Carrie Perkins : I'm forty five and studying gcse biology. The more I learn the more incredible our world becomes. The more I learn the more I can understand what people like Elizabeth are devoting their lives to understanding. Thanks Ted Talks.

Bauss : so smoke weed and relax

bueno bars : Mitochondria is the powerhouse of cells

Salvador Hirth : After watching this informative video, couples can now include a new argument to stop discussions: " _enough! you are shrinking my telomeres! "

MisterRabbitEars : Fittingly enough, those who gave this talk a thumbs down fit the speaker's description of the short-telomere crowd.

Michael Hartman : While I have followed her work for some years, this is the first time I have seen her speak. She is such a charming person. Thank you.

Toon M : Looked like Hillary Clinton in the thumbnail.

Yadi Anyankah : How does our nutrition affect our telomeres?? Animal based in contrast with Plant based???

The Terrible Puddle : My god I thought it was Hillary at first

Mempo : that was incredibly good! ty for the video :)

David Hoar : I love this lady! She has a silly vibe to her despite being so knowledgeable and intelligent. Amazing point being made as well, I don't want to undermine what she's talking about, it's the correlation between your own thoughts and your body.

Robert : Can someone explain to me my question. (An Unethical Question FOR SCIENCE) Since telomeres gets shorten as dna divides, the telomeres in our sperms/eggs should be technically be new right? Can't we do something about that since we actually produce new full length telomeres in sperms/eggs everyday/month

saadick hurre : Thanks toTed Talks and to this great Scientist.

justdoit1200 : I didn't know Julia Childs moonlighted as a scientist

creative bizz : uplifting and informative and blessing for the few with open hearts and willing minds

HOTBALLZ : Yes, women you are getting there. One step at a time. This is a step in the right direction. Intelligence, facts, these are the things we need from you. We can't have men do all the work.. We must unite and create double the innovation. That will not happen as long as you are fixated on your emotions. If this strikes you as offensive, those would be emotions. Those are in your way.

N Silva : Gives new meaning to the expression 'unraveling from all the stress'.

BMX: All Encompassing : One of the most engaging TED talks I've heard

Alex Park : Too bad that powerful corrupt elites will get this first.

The Ultimate Reductionist : Tetrahymena cells: never heard of them. This is news to me, which is good.

leadfoot9x : *Where have I heard that the impact of telomere length on health has been exaggerated, and that most people don't actually reach an age where it becomes relevant?*

Biological Statistics : This is how the school systems are killing young kids by stressing them on the daily.

boson96 : This lady is still young at heart.

ferkinskin : Wonderful and fascinating talk from a lovely lady! Excellent!

Bankside1997 : I love Hillary Clinton's new look.

Lajwanti Shahani : Amazing how science finds evidence from things and places we would never consider. Excellent talk :)

Mike Be : Man shall not live by bread alone. But by every word that proceeds from the mouth of God. Matt 4:4.

Adrian : What an engaging talk! I can understand why one would obsess over this topic, given the potential.

antonïa durán : Not only a sweet and funny woman, but super smart, curious and wise! I'd love to sit and hear all she has to say about the wonderful biology <3

Dylan Lundsten : I wonder what effect the use of marijuana and other substances over time has on telomerase

Ryan Clark : Now I'm stressed out...

Birgit Fischer : Now with the Nobel prize proven: From the mind, the attitude towards distressing situations into the cells ... wow what an amazing scientist lady gives us her insights on how to enhance our youth "inside". Thank you, great share!

Divya Dasagrandhi : Amazing talk. Thank you for revealing fascinating facts.
