In this episode of Death Clock, Brent is joined by epidemiologist David Rehkopf to unpack the science behind "Blue Zones"—regions of the world where people live significantly longer than average. They dive into what these places have in common, how public policy and inequality impact life expectancy, and whether it's possible to build healthier communities by design. It's a conversation about environment, economics, and the invisible factors shaping how—and how long—we live. He's a wonderful guest, hope you enjoy.
