You’ve heard it a million times: Drink eight 8-ounce glasses a day. That’s 64 ounces. Sounds simple, right?

Here’s the kicker: That rule came from nowhere. A 1945 nutrition board said we need about 2.5 liters daily. But they forgot to mention that most of it comes from food.

So, is 64 ounces a magic number? Nope. It’s just a handy starting point. Think of it as the minimum suggestion, not a law.
