I not as optimistic as the original poster about reversing/slowing aging within our lifetimes. It is almost Singularity like thinking ala Kurzweil. Stopping telomere shortening without cure for the deluge of cancers that would follow seems unlikely. It may happen eventually for some portion of populace(think Altered Carbon like split of haves and have nots) but not within our lifetimes. Meanwhile, I have to come to grips with my mortality as a 40+ year old who knows he will not get good at anything where he has to start from a scratch.
