I've been reading some articles on studies that say a faster metabolism may not necessarily be a good thing. They've been linking longevity and youth to slower metabolisms and eating less. The jist of the points are that if you eat less (significantly) you can increase your lifespan by a couple of years and maintain your youthful appearance and staying ahead of the bell curve. It has something to do with slowing down cellular breakdown which they don't know why it happens when a person eats significantly less (somewhere in the neighborhood of 500-700 calories a day). Having high metabolism makes you want to eat more thus you don't benefit from the effects of eating less.
I guess for me that would explain why a lot of track stars and swimmers look like they're 60 years old by the time they hit their 40's.
