I had the opportunity to witness the presenation by David Harrison today [1]
for which I had high hopes that I don't think were fullfilled. I don't think
that he made the case for his premise sufficiently.

However, he did bring up some of the IGF/GH/CR topics/issues extensively with
regard to various strains of mice. This seems pretty unavoidable at this point.
Energy consumption and/or the regulation of energy consumption does seem to effect
longevity.

Joao makes some very valid points regarding other physiological changes
that take place under CR. I think the message here may be that aging
is a multi-factorial process (as the evolutionary biology of aging perspective
would suggest). So "low fat reserves" may translate into some
extenstion in longevity. Then we want to know *why* that is the case
and what else are we missing to explain the complimentary longevity
extending effects.
