God commands us each to take care of the body that He gave to us. On the day of judgement He will ask us each how we took care of the body He gave to us to take us through life. It was in 1976 that I fully realized that I am going to get old and die before the age of 120, and that everyone else alive will too, including those that I love most. So in 1976 I founded the Carl I. Bourhenne Medical Research Foundation to research the best ways to stay youthful, and to live the longest life possible. I received Federal and State tax-exempt status for the Foundation, and we've been researching long life ever since. The Foundation is still active and still researching the ways to live the longest life possible. In 1988 I returned to school and earned a Master's Degree in Gerontology, the study of the aging process. My Master's thesis was a work entitled "How To Live The Longest Life Possible". In 2008 a member of a UCLA anti-aging group asked to join in and has been active in the Foundation ever since. I am 82 years old now, have no health problems, take no medications, run a mile and a half every day, lift weights four days, and am sexually active most days. I feel great all the time. My blood pressure, cholesterol, and sugar are always normal. The oldest PROVEN lifespan in the history of man was a woman named Jeanne Calment, who died in France in 1997 at the age of 121 years 164 days. No one else in history has ever been proven to have lived that long. Each of us will die well before the age of 120. Research has shown that our human genes can support an absolute maximum of about 120 years of life. No one alive today will likely live that long. Relying on 42 years of research, this book describes all of the 13 health factors which we have control of to live the longest life we possibly can. Nothing in this book is optional. All 13 of its lifestyle practices are necessary, or youthfulness, health, and years of life itself will be lost. Take care of yourself and your health as God commands us all to do, and you can have a great life looking good and feeling good for as long as possible. Carl Bourhenne, MA Gerontologist
