What truly helps people live longer, healthier lives? In this episode, we talk with journalist and author Ken Stern about the science behind longevity and why social connection may matter more than diet or exercise alone. From loneliness being compared to smoking 15 cigarettes a day to cultures that keep older adults engaged through work and community, we explore how purpose, relationships, and social structures shape healthy aging.
