In this week's podcast, Professor Luke O’Neill dives into the fascinating world of tech billionaires and their obsession with extending human life. He takes a closer look at four high-profile figures—Larry Page, Peter Thiel, Brian Johnson, and Jack Dorsey—and explores their personal and financial investments in the science of longevity.

From bizarre diets to blood transfusions and even cryogenic preservation, Luke unpacks the sometimes extreme measures these men are taking to live longer. He also visits Calico, a Google-backed biotech company where around 150 scientists are studying the biology of aging—research that includes creatures like naked mole rats and bats.

Luke examines how wealth impacts life expectancy, discusses the current global average lifespan of 73 years, and explores the scientific debate around whether humans might one day live up to 150. He also offers realistic, evidence-based tips for anyone hoping to extend their own life—no billionaire status required.

💡Takeaway:

You don’t need to be a tech mogul to live longer. While billionaires explore the edges of science, simple, proven lifestyle choices may still be the most powerful tools we have for a longer, healthier life.
