Most of the good advice I would summarize as "do what athletes do to achieve higher performance, minus the stuff with known downsides." So, periodized training, quality sleep, managing gut health with a mix of probiotics and fasts, occasional tests to homeostasis to help your body recalibrate. But not the extreme diets, performance-enhancing pharma, heroic training sessions.

The way in which I've noticed most people get themselves in trouble when they didn't start from a position of impoverishment is simply because their response to problems is to, instead of noticing and addressing them, to normalize them and spend their energy making arguments to change nothing. Which is basically baby behavior: "no sleep, no food, no potty, wait why am I crying". Everyone does end up being in "poor health" someday, but it's often a case of how long you want to continue to struggle and preserve what you have, and some people seem to give up when they're, like, 17 years old.
