National Geographic Explorer and best-selling author Dan Buettner has traveled the globe to uncover the best strategies for longevity, which he found in the Blue Zones: places around the world where higher percentages of people enjoy remarkably long, full lives.

In The Blue Zones Secrets for Living Longer, Buettner returns to Sardinia, Italy; Ikaria, Greece; Okinawa, Japan; Costa Rica's Nicoya Peninsula; and Loma Linda, California to check in on the super-agers living in the blue zones and interprets the not-so-secret sauce of purpose, faith, community, down-time, natural movement, and plant-based eating that has powered as many as 10 additional years of healthy living in these regions. And Buettner reveals an all-new Blue Zone—the first man-made Blue Zone yet explored.

Throughout his two decades of research, Buettner has worked with some of National Geographic's top photographers—including David McLain and Gianluca Cola—to document the healthy habits of the world's longest living communities. In this informative collection, their work punctuates Buettner's lively text, offering a beautiful introduction to the Blue Zones and a companion to fans of the Blue Zones Netflix series.
