Book excerpt: Why do we believe that aging is the cause of most of our problems as we get older? Age and aging actually have much less to do with it than you think. Live Young, Think Young, Be Young challenges our assumptions and beliefs about aging, and provides a fresh, new understanding of how and why we grow old. It will make you think differently about little things in your daily life that accelerate the three “mega” causes of getting old. In the end, this book is about courage and resilience—the courage to change what can be changed and the resilience to accept what can’t be changed. Together, they provide a powerful plan for staying young in body, mind, and spirit.
