Dan Buettner has spent more than two decades studying the five places on Earth where people live the longest, healthiest lives—the so-called Blue Zones. But the most important thing he has learned is that none of these people are trying to live longer. They don't track their steps, take supplements, or pursue anti-aging strategies. Longevity, Buettner argues, is a byproduct of living in an environment where the healthy choice is also the easy, unavoidable choice. The real secret is not willpower; it is design.

The Origin and the Power Nine

The Blue Zones project began in 1999 when Buettner, then a journalist solving mysteries for National Geographic, learned that Okinawa, Japan, was producing the longest-lived, disability-free people in the world. He was hooked. With funding from the National Institutes on Aging, he assembled demographers to find other populations where people were living eight to ten years longer than Americans. Because only about 20% of lifespan is dictated by genetics, these populations offered a perfect study group to find common denominators. The result was the identification of five Blue Zones: Sardinia (Italy), Okinawa (Japan), the Nicoya Peninsula (Costa Rica), Loma Linda, California (among Seventh-day Adventists), and Ikaria (Greece).
