Most of us heard this all of our lives, “Doctors recommend drinking 8 glasses of water a day” (The so-called ‘8x8’ rule. Each glass ~ 8-10 ounces or about 240-300ml.)
Back in medical school, we medical students were told the same thing in our Nutrition class. No explanation. Just a simple statement on a sheet of paper and not unlike a mathematical postulate, all of us wide-eyed students accepted it as the gospel of medicine- from the ‘Medicine Gods’…in the ‘House of Gods’.
