Here's a recent 60 Minutes show about a substance called resveratrol. Resveratrol is found in red wine and has been proven to help with anti-aging. Resveratrol supplements are still in testing phase. We won't be able to buy them anywhere for about five years. But they may have the potential to turn a 90 year old into a 60 year old in terms of general health. In the meantime, we can slow aging the old-fashioned way, by eating well (and less) and exercising regularly.
