What happens when we all live to 100 or when most of us at least come close to it? By 2050, the world's centenarian population, those aged 100 or more, will increase eightfold, potentially upending health care, personal finance, retirement, politics and more. William J. Kole, author of "The Big 100: The New World of Super-Aging," examines the forbidding bleakness, as well as profound policy, societal, and lifestyle solutions that can brighten the future for us all.
