    I don't think this study is complete. They didn't control urination duration for beer consumption.

    Or coffee - with or without beer. :rofl:

    Every experimentalist on PF starts to look for his stopwatch.

    Age and/or an enlarged prostate are two other factors.

    Note: std dev == 13 seconds. Except for the beer problem, which most mammals do not have, I think this handles old age and prostate issues. Plus when pelvic matters were evolving, I'm pretty sure we can flatly state 'early hominids did not brew beer'.

    Oh well, so much for any scientific value in the thread.... Humor, yes. Note that all the humor seems to have arisen from the male sector of PF'ers. It's all good -- Mozart loved potty humor, too.
