If there's one thing we know about life expectancy in the US, it's that wealthy communities have long life expectancies and poor communities have shorter life expectancies. But some poorer communities far exceed their peers in terms of health outcomes and length of life. Experts will tell you that “place matters"—but they can’t tell you exactly why.

In Episode 1 of Century Lives: Place Matters, we visit Presidio County, Texas. It’s one of the poorest places in America and one of the top ten longest-lived counties in the nation. We explore the extraordinary story of Presidio—how the community flourishes despite its poverty and distance from health care, and what the rest of us can learn from its longevity.
