The Blue Zones and The Secret of Longevity

        Dan Buettner is the team leader of  "The Blue Zones" which is a longevity research project funded by National Geographic. They are studying human longevity in various cultures around the world. In his book "The Blue Zones", Dan Buettner outlines the healthy habits, the longevity diets and the cultural and familial values that each longevity society upholds.
The name for the project was coined after Dan's team happened to be using a blue marker to circle areas with high rates of human longevity on a map. A blue zone is specifically a geographical region somewhere in the world that has exceptionally high rates of longevity. For example, Okinawan longevity is the best in the world, per capita. One in 2,000 Okinawans can expect to make it past 100, whereas the average American has a 1 in 100,000 chance (according to statistics from 1990).
