The standard “wear and tear” story of aging may be incomplete. Dr. Peter Lidsky—a virologist and evolutionary biologist argues that aging is programmed. He says aging can be an adaptive strategy for controlling pathogens, a concept he calls the “pathogen control hypothesis.”

In this episode, we dig into the evidence behind this idea, the immune system in aging, and what his theory means for longevity interventions.
