It’s a question that for centuries has enticed explorers to travel the globe and many others to suffer through everything from chemical peels to bizarre diets. Is the secret in a good attitude? A lasting marriage? Strenuous exercise? Can we control it at all? Leslie Martin, along with Howard Friedman, is the author of a new book called “The Longevity Project: Surprising Discoveries for health and Long Life from the Landmark Eight-Decade Study.” Leslie Martin talks about the book, and dispels some long-held myths about longevity.
