Diet definitely helps. Same with being in better shape. Likely many many factors.

Agreed. I heard some doctor who spent time with the Maasai (can’t remember who) say they only drink a liter of water a day, often less. Which is wild considering they live in Africa and are very active.
I’m typically a liter or less a day too unless I get a strong sweat going.
Feel like that was the norm forever.
