Understood, but what you and he seem to be implying, is that there is a
direct correlation between age at death and "rate of aging".
Also, you seem to be making an apriori assumption that, whatever
mechanisms are ultimately found to be involved, (in CR or some unknown
analogous method), they cannot be significantly improved upon, even
after they are well understood.
This all seems very speculative to me.

It seems to me that he must be part of a small minority.
