We really need to spread the word to the Gen X, Y, Z, and alphas, so that their future selves will thank them. My younger son is a natural athlete (obviously thanks to my wife, not me), and he gets the message, and, as a doctor of physical therapy, freely shares it with his patients in his calm, non-didactic, lead-by-example demeanor. The Fountain of Youth does exist, and the only cost of admission is a bit of self-discipline. Bicycling makes the cardio exercise part of the equation easy for me. My wife's passion for healthful eating makes the diet part of the equation much easier, through mutual reinforcement.
