Book excerpt: What if you could stay younger longer? What if you could change and control the way you age? What if, biologically, you could become ten or twenty years younger than your actual age? What if you could learn to positively stress your body to become the best version of yourself? What if you could maximize the benefits of exercise and get the results you want faster without wasting time? What if you were given access to information that only a small group of scientists know? If any of these what ifs matter to you, and you want to know the answers with scientific certainty, then we should talk, and through these pages, we will. Simply by timing when to eat, what to eat, and when to exercise, aging becomes a malleable disease. We can change it. We can reset the clock! And I will help you do just that. A.C. Kalfus
