Until recently, almost all researchers believed that the aging process was too complex to find drugs that could slow it. Then geneticists began to uncover single genes that could dramatically extend the lifespan of laboratory organisms such as yeast, worms, flies and mice. The genes underlie the effects of calorie restriction diets, which may delay aging. If eating less can extend a healthy life span, can drugs be taken to fool the body into thinking it’s on such a diet? Larry talks with anti-aging experts about the latest research in the quest for longer, healthier lives.
