Water is great for hydration without filling you otherwise. Like, say you need to drink a lot of fluid because you are really active, you would probably get sick of milk pretty quickly.

If you're replacing sweat, wouldn't you want sports drinks?

But anyway, in most cases, the fact that drinking milk doubles as a source of food is clearly a benefit. It's hard to explain a common behavior by reference to a rare circumstance.

  • Sports drinks aren’t really good for you, but you definitely can drink a lot more of them than you can milk.

    • The idea of sports drinks is that you can drink them without getting water poisoning. This is only a concern if you need a lot of water because you've been sweating a lot, but I thought that was the scenario you were pointing to.
