Aging is inevitable. We can slow it down a little, but could we ever bring it to a grinding halt? These TED speakers explore how we all might live longer and even better lives. Listen to the full episode here:
  1. What are the secret of centenarians?
    To find the path to long life and health, Dan Buettner studies the world's "Blue Zones," communities whose elders live longer than anyone else on the planet.
  2. Can aging be cured?
    Cambridge researcher Aubrey de Grey argues that aging is merely a disease — and a curable one at that.
  3. How do you make an elderly worm feel young again?
    What controls aging? Biochemist Cynthia Kenyon has found a genetic mutation that can more than double the lifespan of a tiny worm, which points to how we might one day significantly extend human life.
  4. How could technology change the way we evolve?
    Medical ethicist Harvey Fineberg says "neo-evolution" is on the horizon. When it becomes easier to eliminate disease through gene therapy, will we change the trajectory of evolution?
  5. Is aging really so bad?
    Author Isabel Allende is in her 70's. She's got a few wrinkles—but she has incredible perspective, too. She says she plans to keep on living passionately as long as she can.
