Dr. Ezekiel Emanuel, a leading oncologist and bioethicist, distills decades of longevity research into six practical rules for a longer, healthier life. Drawing from his book Eat Your Ice Cream, Emanuel challenges popular wellness trends and focuses on what actually matters: relationships, mental activity, diet, exercise, and sleep. The episode unpacks why many wellness interventions fail, what the science really says about supplements and alcohol, and how loneliness becomes a disease vector equivalent to smoking.
