Genius self-experimenter extends his own life and youth with a simple supplement! Through the secret of proper dosing, a cheap, safe, non-prescription health pill, DHEA, can extend youth beyond midlife, 45-50, when aging sets in, with potentially no end to its benefits. Leonard Carpenter's book on his unique discovery, titled DHEALTHY Never Get Old - How I Live Infinitely Without Aging, shares his multi-year practice of not aging. Carpenter's detailed account explains how the aging process is hormone-based, why it limits animal lifespans to a narrow window, how it evolved, and how to supersede it. His longevity regimen has been a do-it-yourself project, but he has worked closely with physicians to defeat problems like shingles, prostate, arthritis, etc. This book, with bibliography and notes, with a forward by an MD, traces his inspiration and discovery with details of sourcing, dosage, benefits, and cautions he's encountered. It also offers Leo's Longevity League, a support service that makes the product available in the most convenient form and shares insights that can enlighten and update other experimenters. Not being a medical professional, Leo cannot prescribe or recommend any treatment, even this one that is natural to the human body. But he can share his own findings in this book that can be a lifelong (i.e., infinite) resource. It also contains Carpenter's longtime and nearly infallible method for fighting off and curing common colds and virus attacks, including Covid-19, using simple household and over-the-counter ingredients in a bonus chapter. To Eternity, and Beyond!
