Although looking young, longer, is a byproduct of this Chinese art, its main purpose is to extend quality of life into old age (EQOL), i.e., good health and fitness into your latter years. Everything you did for fun, enjoyment and sports in your forties, you should be able to do in your seventies and beyond. This ancient art is all natural...no drugs, pills, lotions, potions, hormones, etc., none of which will make you look younger or live longer in good health (just make some people rich). Best of all, there is no restrictive diet, no strenuous exercise, no time consuming requirements, and as you progress, you will feel better, look better and be able to take advantage of the last twenty years of your life, instead of debilitation, illness, pain and requiring a caregiver. It will require many lifestyle changes, but nothing that causes stress, great inconvenience or unacceptable restrictions to your life. The main source of information in this book is Grand Master Tian Yong, a woman who is sixty-two at the time of writing and is often mistaken for a woman in her twenties. She doesn't really care about youthful appearance as her main concern is living in good health and fitness to the end of her days.
