I would really like to see more research on the relationship between metabolism and aging (not passage of time, but actual cellular aging, I think referred to as mitochondrial aging?)

I had thought that low metabolism, meaning a low pace, or clock to the body's energy consumption, would imply a slower aging action, but a cursory search on google immediately turned up some research that says it may be just the opposite: that high energy consumption (not food consumption, energy use by the body) in mice seems to lead to greater longevity...

Anyone with a more detailed understanding, please?
