It's true, and I'm tickled that Beth remembered (can I try out my Britspeak and say I'm chuffed?). My posts about the curious habit of students clutching their bottles of water as they enter class go back a long way. Here's an excerpt from a somewhat later post of mine: Re: It really is 8 glasses a day!

And now along comes Dr. Chan and says it's true after all. But there is reason for caution. Her study is, once again, correlational. She makes the appropriate disclaiming noises in her paper, but has been less cautious in her correspondence with me and, I think, also in interviews. She really thinks it's causal, and is quite enthusiastic about her work, which has received a quite impressive degree of publicity.... [I go on to deconstruct her pro-water report, which apparently no one still remembers]. There was also, BTW, a report last year in the British Medical Journal (Vreeman, R., & Carroll, A. (2007). Medical myths. BMJ, 335, 1288-1289) which also debunked the 8 glasses, and which we discussed at the time. So it must have been a slow day for news. I guess we're getting tired of hearing about Hillary's latest lie. Stephen ----------------------------------------------------------------- Stephen L.
