In How to Live Forever, Encore.org founder and CEO Marc Freedman tells the story of his thirty-year quest to answer some of contemporary life’s most urgent questions: With so many living so much longer, what is the meaning of the increasing years beyond 50? How can a society with more older people than younger ones thrive? How do we find happiness when we know life is long and time is short? Freedman finds insights by exploring purpose and generativity, digging into the drive for longevity and the perils of age segregation, and talking to social innovators across the globe bringing the generations together for mutual benefit.
