Sex differences in longevity and therapeutic responses may exist and require further exploration.

“now the limitation of course because it's humans is that we're kind of stuck with doing that in blood and we don't know if the same thing might be going on in the brain or the liver although again i guess from autopsy studies we could probably figure that out now but we do have the tools now to do a lot of this we could do muscle biopsies is it the same in the blood and the muscle that's a possibility um so you know my feeling is that we have yet to really explore these sex differences in any depth and that we may end up having somewhat different therapeutics in women and men once we start looking into exactly how these things work out between the sexes”
