After a chance encounter with an extraordinary ninety-year-old woman, renowned gerontologist Karl Pillemer began to wonder what older people know about life that the rest of us don't. His quest led him to interview more than one thousand Americans over the age of sixty-five to seek their counsel on all the big issues- children, marriage, money, career, aging. Their moving stories and uncompromisingly honest answers often surprised him. And he found that he consistently heard advice that pointed to these thirty lessons for living. Here he weaves their personal recollections of difficulties overcome and lives well lived into a timeless book filled with the hard-won advice these older Americans wish someone had given them when they were young.
