This book is for and about a growing group of people who are leading a movement that is utterly changing our traditional attitude toward midlife, which has become a time of opportunity. Today, people in their fifties and sixties are involved in a second social revolution: Rather than becoming spectators of their kids' lives, they're doing amazing things with their own. Not content to walk quietly into their golden years like their parents, they are extending their active lives - working, traveling, creating, seeking, spending and having sex and adventures just as they did in their 20s. Only now they've got the money and the energy to do it on a new set of terms. The heart of the book is made up of profiles of 30-40 men and women who've remade their lives in fascinating ways. Dozens of stories, based on in-depth first-person interviews, reflect this sociological and cultural phenomenon.
