TED talk by biochemist Cynthia Kenyon on how a simple genetic mutation can double the lifespan of the worm C. elegans, and what that suggests about extending healthy human life.

Harvard geneticist David Sinclair discusses his book Lifespan at Google. He covers the biology of aging, lifestyle interventions and possible future ways to slow or reverse it.

Physicist Geoffrey West speaks at an FQXi conference on time about complexity and scaling laws. He covers how metabolism, growth and lifespan scale across organisms and how the same mathematics applies to cities and companies.

A Kurzgesagt animated explainer on whether aging could be cured within our lifetimes, made with Lifespan.io and the LEAF foundation. It introduces the idea of treating aging as a medical problem.
