I don't have a link to it, but I remeber a study shwong men's heart rates inrceasing, stress hormones rising and all the symptoms of physiological discomfort rocketing when men are dragged along by their better halves to shop. I know I experience that. It's the seemingly directionless way women shop - either it's very inefficient or it's very clever and I haven't figured out the algorthim. When I go shopping, I'm in, I'm out like a rat up a drainpipe.
