In this episode, Xavier Bonilla has a dialogue with Michael Gurven about humans living for seven decades. They discuss our evolution for seven decades, post-reproductive life, healthspan vs. lifespan, subsistence populations, multigenerational cooperation, older age, seven decades in the future, and many more topics.

Michael Gurven is an evolutionary anthropologist and professor at University of California-Santa Barbara. He has conducted fieldwork for two decades with South American indigenous populations, and his work takes an evolutionary perspective on behavior, health, physiology and psychology. Since 2002, he has co-directed the Tsimane’ Health and Life History Project to better understand how aspects of environment and lifestyle affect health and lifespan in subsistence-level societies. His research applies an evolutionary lens to help inform our understanding of today’s complex diseases. He is the author of the book, Seven Decades: How We Evolved to Live Longer.
