If couch-potato lab mice had beach-body dreams and if they could speak, they might tell you they’re thrilled by advances in the science of exercise and calorie-restriction (CR) mimetics. In recent studies conducted at research centers across the United States, mice have chowed down, fattened up, exercised only if they felt like it, and still...
