The secret to happiness, longevity, and living on is through mentoring the next generation. 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 fifty? 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? In a poignant book that defies categorization, 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. He finds wisdom in stories from young and old, featuring ordinary people and icons like jazz great Clark Terry and basketball legend Kareem Abdul-Jabbar. But the answers also come from stories of Freedman's own mentors-a sawmill worker turned surrogate grandparent, a university administrator who served as Einstein's driver, a cabinet secretary who won the Presidential Medal of Freedom, and the gym teacher who was Freedman's father. How to Live Forever is a deeply personal call to find fulfillment and happiness in our longer lives by connecting with the next generation and forging a legacy of love that lives beyond us.
