Blue Zones: Lessons From the World's Longest Lived.

What began as a National Geographic expedition, lead by Dan Buettner, to uncover the secrets of longevity, evolved into the discovery of the 5 places around the world where people consistently live over 100 years old, dubbed the Blue Zones. Dan and his team of demographers, scientist and anthropologists were able to distill the evidence-based common denominators of these Blue Zones into 9 commonalities that they call the Power 9. They have since taken these principles into communities across the United States working with policy makers, local businesses, schools and individuals to shape the environments of the Blue Zones Project Communities. What has been found is that putting the responsibility of curating a healthy environment on an individual does not work, but through policy and environmental changes the Blue Zones Project Communities have been able to increase life expectancy, reduce obesity and make the healthy choice the easy choice for millions of Americans.
