As the first members of that huge generation known as the baby boomers begin to reach retirement, they are clearly more active and in better health than were earlier generations reaching that milestone. The boomers are looking forward to some two decades or more of what they believe will be an active, enjoyable third stage of life, given increases in longevity. What few of them have spent time contemplating, however, are the long-term problems that those extra years can bring: Will they be able to afford their new longevity? Will they remain healthy until the day they die? Who will care for them when they no longer can care for themselves? Beverly Goldberg examines these questions in the latest issue brief from The Century Foundation.
