New Theory of Aging: Humans vs. Pathogens
Thursday, 16 October, 2025
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.Episode Show Notes: https://livelongerworld.com/p/plidskyFind me: https://x.com/aasthajs My longevity products: https://www.livelongerworld.com/p/2024TIMESTAMPS:0:00 — Aging ≠ Wear-and-Tear3:44 — The Case for Programmed Aging8:48 — Why Program Aging at All?11:09 — The Pathogen-Control Hypothesis14:26 — Why We Get “Sick Time”24:37 — Rising Lifespans, Explained27:36 — Bowhead Whales’ Longevity Edge31:15 — Why Lone Animals Don’t Live Forever34:00 — Planaria: The “Immortal” Worm35:00 — Do Infections Speed Up Aging?36:46 — When Immunity Starts to Slide38:17 — Why Fertility Has a Deadline42:49 — Extending Life via the Immune System1:00:35 — How Honey Bees Rejuvenate1:10:50 — Can We Tackle Aging?
