The Politics of Vitamin Research
The main evidence that that is not so, and that the more resistant you
are naturally, the harder it is to improve on you, is that until fairly
recently mortality curves in developed nations were getting more
rectangular even at ages around the life expectancy. We may now be
close to the point where medical treatments that can help anybody can
help most people, giving the recent pattern (no more rectangularisation
but rather a progressive right shift in survival, i.e. all deciles of
the mortality distribution moving to older ages at roughly the same
rate). And yet, the acceleration in that right shift seems to be continuing.
Hang on -- if so, surely you would have to look at **all** comparisons
between species with similar caution? That seems likely to be rather over-restrictive.
Absolutely. But so might humans.... and certainly so do the cloned
mice that you mentioned initially in support of your position.
Yes. One of the main differences, a decidedly relevant one, is that
the intestinal stem cells express telomerase.
