My wife just compared all this tech-adjacent extreme longevity focus in men to anorexia in women. A physical manifestation of anxiety and lack of control. And now I can't get the thought out of my head. Spot on.

And she followed up with the take that this is why women like dad bod over the obsessive-fitness figure: It signals positively about the underlying psychology and priorities. Like Jung said: "Mentally unhealthy people are usually fanatics of healthy lifestyles".

@bryan_johnson I also observe that people who do all the right things with the wrong genes keep dying early, and people who do all the wrong things with the right genes keep soldiering on. Think we have to be honest that health, like IQ, is largely heritable trait. Even if we can nudge it.
