This week is a rebroadcast of a discussion Cheryl Fusco Johnson had with Dan Buettner. Dan is the founder and Chief Executive Officer of Blue Zones and the author of "The Blue Zones: Lessons for Living Longer From the People Who've Lived the Longest".  In 2004, Dan worked with National Geographic and some of the world’s top longevity researchers to identify places around the world where people lived measurably better. His research proved the basis for "The Blue Zones" book. Dan has also written "Thrive: Finding Happiness the Blue Zones Way" and used a similar approach to find the areas with the happiest people.
