KQED's QUEST recently aired a piece on the science of calorie restriction, discussing the past few years of research with scientists working at the Buck Institute for Age Research: "Have we found the fountain of youth? Scientists are discovering ways to make animals live dramatically longer through calorie restriction. While the technique has attracted a small, but devout following, skepticism abounds. ... Alzheimer's, Parkinson's, cancer, stroke, and arthritis have one thing in common: age. By focusing on the connection between aging and disease, scientists at the Buck Institute for Age Research are striving to develop diagnostic tests and treatments that will prevent or delay these conditions." Calorie restriction is not the fountain of youth for us - but it is a helpful way to raise our chances of living to benefit from the real rejuvenation medicine of future years. No fountain of youth exists today, but it is within our power to band together, research, and find out how to build medical technology to repair aging and make the old youthful once more.
