The 74-year-old author, John M. Memory, realized in recent years that he has much important information that is seldom or never taught in college and university courses. After checking course descriptions of a major university in the Southeast, he undertook writing this book. Though John is not a health expert, he has had significant scholarly and professional experiences relating to health that have helped him in writing the 17 chapters about health. John learned much from using non-medical, life style approaches in preventing the fifth through the second most feared diseases–diabetes, stroke, heart disease, and Alzheimer’s. For example, he rejected his doctors’ recommendations of taking a statin drug and, instead, has performed a heart and brain health routine he developed in 1982, with excellent results. Regarding the most feared disease, cancer, he learned in 2018 that, long after failed prostate surgery and radiation treatments, three alternative, holistic anti-cancer approaches have stopped the advance of his aggressive recurrent prostate cancer. In other chapters, John discusses the dangers posed by rampant ethnocentrism and xenophobia, how to teach moral behavior to children, the joys of frugal living, the importance of moral courage in work and government, origins of religion, the importance and challenges of high-risk activities and decision making, and much more. Since many people will disagree with him on one or several subjects, John hopes that readers will focus on chapters that can be most helpful for the reader. Join the author on a thought-provoking journey that revolves around Mysteriously Missing College Courses.
