Last time I chatted with Dan Buettner, he introduced my radio audience to the concept of “blue zones,” those places on our planet where people seem to live the longest . He also taught us why they have such remarkable longevity. Now, in The Blue Zones of Happiness, he uses further research to show us why these folks are also among the happiest in the world and what key strategies we can impliment in our own lives to find our happy place.
