Most of us will live long, useful lives, and it's not just our great-grandchildren who will get to do that. The story of aging is not one of steady decline and decay; we need a new report based on solid research, not scare stories. The world's population is getting older quickly, and people are living longer. This has brought up questions like "why we age," "how do we age," "how long can we live," "how to stay healthy," "how to prevent and treat diseases in old age," "what are the prospects for healthy aging and longevity," and so on. This book has answers to all of these questions and more. In this book, I tried to tell you everything you need to know to keep your senior's health in good shape and help them live a long healthy life. I use real-life examples to show what our new, longer lives will be like and what needs to change so that we can all make those extra years more productive and fun.
