The Danish concept of hygge is delightfully cozy, but Japan's ikigai could prolong your life! This bright and breezy philosophical guide explains how ikigai “which translates roughly as 'the happiness of always being busy'” is a key element in the remarkable longevity of residents of Okinawa. (And don't worry…it's a different kind of “busy” than many Americans are accustomed to!) Complete with interviews with Japanese centenarians, this warm and inspiring book shares many interesting ideas and “secrets” to ponder and, possibly, incorporate into your own ever-more-fulfilling lifestyle!
