Years ago, I suggested to Phil Fons that since he was a man of such personal conviction about people taking charge of their own health, the Institute of Continued Learning participants at Dixie State in St. George, Utah would benefit from his expertise. He followed up and taught a well-attended and enthusiastic-response class for eight years. This book has grown out of his research and lecture notes from those years. Phil was working on his manuscript with his wife, Evelyn's able assistance.Unfortunately, at age 92, he died and left her to carry on his dream of sharing his research and personal-experience results with the students who had begged him to write a book. His desire to inspire them with positive guidance for living to their highest potential physically, emotionally and spiritually fell to Evelyn to complete in book form. In Pursuit of Optimum Health contains a wealth of practical, plain common-sense suggestions delivered in Phil's scientific yet folksy style. As a space engineer with Rocketdyne, research was his natural bent. When Evelyn was diagnosed with cancer, he consulted every study and avenue medically and holistically to cure her-without resorting to surgery, radiation and chemotherapy- if those "treatments" could be avoided. His research, interviews and common sense led him to alternatives that called for herbal and unprocessed health-food nutrients and oxygenating the body with appropriate exercise. He also sent Evelyn to a health spa for three weeks to learn those techniques. She has been cancer-free for over thirty years! She never had surgery or endured radiation or chemotherapy. She healed herself through the techniques she learned and lives by them to this day. Phil's popular class: "You Don't Have to Die From Cancer" expounded on his passion for being positive, treating your body with respect and support, and committing to a healthy lifestyle. Evelyn, now at age 92 herself, is living proof that a change of lifestyle works. This book has lifesaving information, much of it recorded no where else unless you personally consult the studies Philresearched. In Pursuit of Optimum Health is crammed with suggestions for preventing life-threatening diseases and improving your quality of life for those coping with serious ailments, such as cancer. I am honored to have been asked by Evelyn to write this foreword in support of my late colleague and friend, Phil Fons.
