Have we found the fountain of youth? Scientists are discovering ways to make animals live dramatically longer through calorie restriction – a diet that requires eating at least 30 percent fewer calories than normal. While the technique has attracted a small, but devout following, skepticism abounds. QUEST investigates why we age and what the societal costs are for living well beyond 100.
