Are there people who hit 120 who were not in good shape at 77? If not, then it seems like improving your status at 77 is a necessary step.
Beyond that, if you wouldn't do it for an EV of 1 decade, but would do it because it gives you a chance at hitting 120, I think our priorities are very different. (Indeed, referring to 120 as the 'usual' limit seems odd to me. It's five years longer than any man has survived, and there are only 6 men above 110. I wouldn't call that usual- indeed, the 'usual' limit seems like it would be the median age at death. But I count my remaining lifespan up from 0, which is not a universal approach.)

Necessary, but not sufficient, even if one grants the claim that CR results in an overall improvement (rather than a dramatic improvement on some age-related diseases and unknown compensating penalties).

Yes. A treatment that gives another 20 years and br...
