To live to be 100 is great but not if you're feeble. This book will show you how to be healthy and happy at 100. Other "live to 100" books stress longevity factors, such as exercise, nutrition, relaxation, hormones, and strong relationships. Some authors have written about longevity from research studies; others from investigation of centenarians; and a few from personal experiences. "Young at 100" is based on all three aspects initiated by the author's quest for longevity. Two outstanding athletic and intelligent centenarians (age 103 and 106) are featured. "Young at 100" is the most comprehensive book ever written on living to 100. Chapters include: exercise (all types); nutrition (foods, nutrients, drinks); relaxation techniques; relationships; humor; diversions (hobbies, vacations); sleep; spirituality; anger and anxiety control; overcoming obesity; dealing with smoking, alcohol, and drugs; and avoiding danger. This book should help everyone — young and old. It is written in a down-to-earth style, and to lighten the load it includes humorous stories and relevant illustrations by Dr. Marvin Herring, a renowned cartoonist and exceptional physician.
