Here’s the truth: your body is weirdly smart. If you’re active, eat fruits and veggies, and listen to your thirst (not fear), you’re probably fine.
Don’t obsess over ounces. Just drink when you’re thirsty, eat your water-rich foods, and laugh at the idea of a universal rule.
So, next time someone asks “how much water?” smile and say, “Enough to keep my pee pale and my brain zippy.” That’s the fun answer. Now go hydrate—but not too much.
