Are you guys old enough to remember Paul Dudley White, M.D., the eminent cardiologist and father of preventive cardiology through exercise? Really cool guy who served as Eisenhower's and LBJ's cardiologist. He believed in cycling, but he thought pushing a big gear was a better than spinning. Oh well, every guy is entitled to one mistake, right?


He also said "A vigorous five-mile walk will do more good for an
unhappy but otherwise healthy adult than all the medicine and
psychology in the world."
