> I don't "run further" because of some random need to do more, but because this is an input into my health, and more health is always better.

Pretty dubious claim. You really think that running and health are related in an even remotely linear fashion? It's likely doing it at all puts you way, way up the effort/benefit curve. Constantly pushing yourself for "better" eventually just becomes a waste of time you could put into something else.

Yeah, and the stress of telling your body that it always needs to do better to survive probably makes you age faster.

There’s diminishing marginal returns from exercise. So there’s probably a sweet spot of how much you want to do it. Same with work. And for many people, same with spending time with friends and family.

There’s an implicit belief in a lot of this thread that more is better and that happiness is down the road of doing more things. That’s stupid and wrong for almost all of us. And ironically, your career, health and relationships all suffer if you push too hard and don’t let them breathe. The real joys are found sitting watching the sunset, with a good meal with the people we love. It doesn’t get better than that.

I mean if you want to split hairs and miss the larger points sure. Yes you can be at diminishing returns so you are right there's a limit to more is better. Not the situation I am talking about here, both fitness wise and economically because frankly 99.999% of people are nowhere near diminishing returns on either of those.
