Dan Buettner's Blog

Dan Buettner is a National Geographic Fellow and multiple New York Times bestselling author. He has discovered five places in the world ­– dubbed “Blue Zones” – where people live the longest, and are healthiest: Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece, and Loma Linda, California.

The concept of “Blue Zones” grew out of the demographic work done by Gianni Pes and Michel Poulain outlined the Journal of Experimental Gerontology, identifying Sardinia as the region of the world with the highest concentration of male centenarians.
