Is this real science or dupication of sci.life-extension?

Pardon the answer of a non-scientist-but-interested-amateur; but I think
cell division-rate is only part of the equation. The DNA of older
organisms is much more at the effect of free-radical attack that leads to
mutation. The more exposure over time, the more mutation and the more
problems there will be dividing successfully.
Well, I think that's close.
