One thing I'd really like to understand re: ageing is why a newborn is essentially 'reset' from an ageing perspective. I appreciate that egg cells aren't constantly dividing during a mothers life but they are still a product of division and contain DNA that can suffer from time based mutations. So if aging is due to mistakes accumulated during either divisions or time then why are children born young? I don't think this is as simple as non-viable embryos are miscarried, there must be something different in the formation of embryos that means they don't carry the aging of their parents...and what clue does that give to cure aging?
