which, IIRC, discussed the notion of an semi-autonomous population of mitochondria in long lived tissues (like muscle) which could be curated over ones lifetime by high intensity exercise stress. Future mitochondria in these long-lived tissues would then not be descended from the poorer performing members who were weeded out through apoptosis.
