Welcome to Happy to 102! Happy to 102 is the first of a series of books focused on healthy longevity, which we define as remaining healthy, active, sharp and happy throughout an extensive lifespan.

We are living longer than ever. Centenarians are the fastest growing segment of our population. Before we know it, 102 just may become the new 75. As we live longer, though, we want to enjoy improved health-span alongside increased lifespan. Happy to 102 lays out all those factors-diet, exercise, sociability, mental challenge, sense of purpose-that make the difference not only in how long we live but in how well we live. Based on groundbreaking scientific research of the longest living people on Earth, Happy to 102 spells out precisely what it takes to delay or escape Alzheimer's and other chronic diseases, slow down the process of aging and enjoy better health in our senior years. With an emphasis on aging in place with in-home care, Happy to 102 unlocks the secrets to longevity and inspires us to live happier, healthier lives at any age.
