how many ounces are we supposed to drink a day?
<answer> People should drink at least eight ounce glasses of water a day. <context> Let’s put these claims under scrutiny. I was a co-author of a paper back in 2007 in the BMJ on medical myths. The first myth was that people should drink at least eight 8-ounce glasses of water a day. This paper got more media attention (even in The Times) than pretty much any other research I’ve ever done.
