The Role of Genetic Damage in Aging

It's primarily that the genome degrades over time beyond the ability of the cell to be useful still. So even if you've not accumulated enough mutations to for that to be catastrophic for your body functioning, you may have accumulated enough. And then like, so some of what causes aging is sort of your body trying to mitigate this damage to extend the lifespan rather than like the example of the senescence cells. It also comes back to the evolution question again, because there is a certain amount of selection for a given lifespan or at least a minimum degree of functionality at a point in time.
