Today, we look inside your body and get familiar with your immune system’s constant vigilance against infection and disease. We also look at your body over time; what happens as you age? Is there a way to stay young? And why do we value that so much?

We turn to the research and insights of the speakers of the Aspen Ideas Health conference for the answers. Aspen Ideas Health runs from June 20 - June 23, and is produced by the Aspen Institute.

Episode five explores the conference tracks Inflamed! and From Lifespan to Healthspan and features Daniel Davis, Marc Freedman, Edinah Masiyiwa, Crystal Hall and Nora McInerny.
