Human bodies aren't built for extreme aging: our capacity is set at about 90 years. But what does aging really mean, and how does it counteract the body's efforts to stay alive? Monica Menesini details the nine physiological traits that play a central role in aging. [Directed by Cinematic, narrated by Pen-Pen Chen].

Cambridge researcher Aubrey de Grey argues that aging is merely a disease -- and a curable one at that. Humans age in seven basic ways, he says, all of which can be averted.

Midlife doesn't have to be a scary time, says entrepreneur Chip Conley. In this short yet profound talk, he takes inspiration from the natural world to reframe our 40s, 50s and 60s as a transitional stage that's full of grace and beauty — and urges us all to make aging aspirational.

The extra candles on the birthday cake, the little lines you notice in the mirror ... aging doesn't always feel good. But remember, age also brings wisdom and balance. Watch these reminders of the benefits that come with age.

We need to feel better about aging in order to age better, says writer and activist Carl Honoré. How? In this spirited talk, Honoré offers a set of simple solutions to combat ageism -- as well as a host of trailblazers and changemakers who came into their own later in life, from artists and musicians to physicists and business leaders.

Tony Wyss-Coray studies the impact of aging on the human body and brain. In this eye-opening talk, he shares new research from his Stanford lab and other teams which shows that a solution for some of the less great aspects of old age might actually lie within us all.

Some works of art stand the test of time; others don't age as well. Using American musical theater as her case study, theater historian Margaret Hall shares a framework of five categories to talk about how art does (and doesn't) remain useful across generations -- encouraging us to address the "growing pains" that all art faces as time and cultu...

More than 40 million people worldwide suffer from Alzheimer's disease, and that number is expected to increase drastically in the coming years. But no real progress has been made in the fight against the disease since its classification more than 100 years ago. Scientist Samuel Cohen shares a new breakthrough in Alzheimer's research from his lab...

When it comes to aging well, having “good genes” (or rather, mutant ones) is key, says Cynthia Kenyon. She unlocked the genetic secret of longevity in roundworms — and now she’s working to do the same for humans.

Why are we so obsessed with age? From quests for youth to immortality, these speakers explore the science of staying alive.

Alzheimer’s and dementia are a heart-breaking reality for millions across the world. Find out what inventors and scientists on the cutting edge of medical research are doing to combat this neurological puzzle.

What controls aging? Biochemist Cynthia Kenyon has found a simple genetic mutation that can double the lifespan of a simple worm, C. elegans. The lessons from that discovery, and others, are pointing to how we might one day significantly extend youthful human life.

For the microscopic lab worm C. elegans, life equates to just a few short weeks on Earth. The bowhead whale, on the other hand, can live over two hundred years. Why are these lifespans so different? And what does it really mean to 'age' anyway? Joao Pedro de Magalhaes explains why the pace of aging varies greatly across animals. [Directed by Sha...

From exoskeletons and robotic arms to the mass adoption of remote work, economist Piyachart Phiromswad explores what seniors need to overcome the physical, mental and societal barriers to employment, a necessary shift in our rapidly aging world. Learn more about how these tools could empower elderly workers and better the world — for everyone.

Can we, as adults, grow new neurons? Neuroscientist Sandrine Thuret says that we can, and she offers research and practical advice on how we can help our brains better perform neurogenesis—improving mood, increasing memory formation and preventing the decline associated with aging along the way.

Alzheimer's disease is the most common cause of dementia, affecting over 40 million people worldwide. And though it was discovered over a century ago, scientists are still grappling for a cure. Ivan Seah Yu Jun describes how Alzheimer's affects the brain, shedding light on the different stages of this complicated, destructive disease. [Directed ...

Twenty-somethings rejoice! From personal finance to finding your passion, these TED Talks can help you through your (first, second and possibly third) quarter-life crisis.

In the pitch-black night, stung by jellyfish, choking on salt water, singing to herself, hallucinating … Diana Nyad just kept on swimming. And that's how she finally achieved her lifetime goal as an athlete: an extreme 100-mile swim from Cuba to Florida -- at age 64. Hear her story.

Aubrey de Grey, British researcher on aging, claims he has drawn a roadmap to defeat biological aging. He provocatively proposes that the first human beings who will live to 1,000 years old have already been born.

The legendary Eva Zeisel worked as a ceramics designer -- whose curvy, sensual pieces bring delight and elegance to tabletops around the world.

Jane Fonda has had four extraordinary careers (so far): Oscar-winning actor, author, fitness guru and impassioned activist.

Some simple (and honestly sort of scary) ways we can potentially prolong human life.

Author Isabel Allende is 71. Yes, she has a few wrinkles—but she has incredible perspective too. In this candid talk, meant for viewers of all ages, she talks about her fears as she gets older and shares how she plans to keep on living passionately.

It's not the passage of time that makes it so hard to get older. It's ageism, a prejudice that pits us against our future selves -- and each other. Ashton Applewhite urges us to dismantle the dread and mobilize against the last socially acceptable prejudice. "Aging is not a problem to be fixed or a disease to be cured," she says. "It is a natura...

Eric Dishman does health care research for Intel -- studying how new technology can solve big problems in the system for the sick, the aging and, well, all of us.

Artist Tony Luciani was testing out a new camera when his 91-year-old mother, Elia, snuck into the background of his photos. The spontaneous images that resulted sparked a years-long collaboration, with Luciani documenting his mom's life and spirit as she lived with dementia. In this touching talk, he shares the stories behind some of their favo...

What makes our bodies age ... our skin wrinkle, our hair turn white, our immune systems weaken? Biologist Elizabeth Blackburn shares a Nobel Prize for her work finding out the answer, with the discovery of telomerase: an enzyme that replenishes the caps at the end of chromosomes, which break down when cells divide. Learn more about Blackburn's g...

At his lab at Stanford School of Medicine, Tony Wyss-Coray studies aging -- and potential cures for it.
