How long does it take for a myth like this to live? Here's Snopes from years ago: https://www.snopes.com/fact-check/water-works-2/ https://www.snopes.com/fact-check/water-works-2/ It cites the LA Times from 20 years ago. But even the NYT covered this before. "No, You Do Not Have to Drink 8 Glasses of Water a Day" (2015) https://physics.emory.edu/faculty/roth/ethics/8glasses-water-NYT.pdf https://physics.emory.edu/faculty/roth/ethics/8glasses-water... That's by the co-author of "Medical Myths" in the BMJ (2007) https://www.bmj.com/content/335/7633/1288 https://www.bmj.com/content/335/7633/1288 ; Which in turn cites “Drink at least eight glasses of water a day.” Really? Is there scientific evidence for “8 × 8”? by Heinz Valtin (with the Technical Assistance of Sheila A. Gorman) in 2002 at https://journals.physiology.org/doi/full/10.1152/ajpregu.00365.2002?origen=app https://journals.physiology.org/doi/full/10.1152/ajpregu.003... . Sigh.
