Journalist William J. Kole, reluctant but newly minted member of AARP, explores the looming era of super-aging—incredibly longer lifespans overall, and eight times more centenarians by the year 2050—through the lens of past, present, and future life at ages 50, 65, 80, and on to 100-plus. What happens to all of us when 65 is merely a life half-lived? Michael talks to him about his book "The Big 100: The New World of Super-Aging." Original air date 26 July 2024. The book was published on 3 October 2023.
