It's commonly thought that if your cells kept dividing the way that they do when you're young and they accumulated genetic damages you'd get cancer more often.

That isn't a satisfying answer because humans can obviously generate germline cells that don't suffer from this issue.

So the question becomes why can't somatic cells repair themselves to be as healthy as germline cells?
