When this water myth came out in the 80s, I remember arguing with some people that not only did people know when they had to drink liquids (hint: they got thirsty), they could get their water out of foods and other liquids.

One person just refused to believe me. She had heard that it must be "pure" water and absolutely eight glasses...no more, no less. About one month after our discussion she came back and admitted I was right. She had checked with an actual nutritionist who told her the truth.

I remember hearing that sodas didn’t count. I recognized it as Puritanism, not science.

Well she came back and admitted she erred...sounds like a person with a modicum of integrity!
