In this episode of Death Clock, host Brent Franson sits down with Dr. S. Jay Olshansky, a leading expert on human longevity, to unpack what that data says about how long we can live. Drawing on decades of research, Olshansky explains why dramatic lifespan extensions (like living to 120 or beyond) may be far less realistic than many in the longevity space believe, and why increasing life expectancy becomes exponentially more difficult over time. The conversation explores the concept of "manufactured time" through medicine and lifestyle, the limits of eliminating disease, and the critical difference between individual gains and population-level outcomes. At the same time, Olshansky shares cautious optimism about emerging approaches that could one day target the aging process itself. He's a great guest, hope you enjoy.
