I'd guess neither, actually. Accumulating errors and failures in cell machinery (apparently correlated with telomere count) result in mitochondria becoming less and less able to perform basic cellular housekeeping functions, so metabolites previously carefully dismantled and recycled get left to build up, and eventually to exude. There is much longevity research directed at this. Some of those pill bottles you see in the supplement section are directed at this phenomenon - "Co-Q10" and L-carnitine are the two current favourites for enhancing aging mitochondrion function, along with omega-3 oil as mitochondria fuel.
