Another bonus question about urine, while I’m pondering the subject: when we are very hydrated, urine looks extremely clear, almost like water. If you are essentially just taking water in and peeing water out when you are very hydrated, is it even worth drinking water at that point? Like, are there diminishing returns to the amount of hydration we can get? (I know there’s those extreme cases of dying from drinking too much water, but that’s not what I’m talking about here)

Take the tube inside a roll of paper towels, hold it horizontally, and pack it with ping pong balls. Now, shove another ping pong ball in one end, and a ball will pop out the other end.
That’s more or less it. Your body can hold so much fluid and you put more in, then some has to come out. If you put enough in in, the bladder will fill up quickly, and if it’s fast enough it can fill faster than stuff is filtered out (so it’s clear).
You do need to drink enough water to keep to flow going (so you can filter stuff out and pee it out). Drink too little, and you you dehydrate (volume of blood goes down, concentration of stuff in the blood goes up, hard on heart and kidneys). Drink too much, and you mess up the concentration of salts and minerals in your blood and your heart can fail.
