This book is an attempt at discussing the various factors that affect and increase a person's longevity—- avoid those that have been known to decrease it and encourage those that were known to increase it. You will learn how to prevent diseases and in some instances reverse diseases with the use of nutrients—minerals, vitamins, essential amino acids, and fatty acids, and by modifying your lifestyle, how you think, act, eat and handle stress in your life. You will learn that people have lived up to 120 to 140 years.
