This podcast explores the advancements in medicine and public health that have significantly extended human lifespans over the past century. However, recent research suggests that we may be approaching a limit to how long people can live, with the average lifespan potentially plateauing at around 87-90 years for women and 84 years for men. While breakthroughs in medical science could extend these limits, the podcast emphasizes that personal lifestyle choices, such as staying connected, being active, sleeping well, practicing mindfulness, and eating a healthy diet, can help individuals live longer, healthier lives even within these constraints.
