people who are actually experts in kidneys and how the body manages water disagree with you. they say thirst is a fine way to go with exceptions being very rare and mostly among the elderly, but that even there 8 glasses of water a day is way more than is necessary. as well the idea that coffee/milk/juice don’t count is also untrue.
