Live Long and Starve

Scientists may have discovered the key to eternal youth: starving. A new report says that strict adherence to an extremely low-calorie diet can extend length of life. This has been shown to work on fruit flies, but now scientists have found the same results with primates. Joining us to explain the study and its implications for humans is Ricki Colman, associate scientist at the University of Wisconsin, who helped conduct the low-calorie experiments.
