Mitochondrial Ageing

I'm passing this link on because it gives an explanation for the effects of ageing down to the mitochondrial and dna level. It's a positive message that explains my faith that as I age I can keep my vitality. The findings need to be confirmed but they fit wider research. Just wanted to provide a reference so I don't forget this.
