"I have a friend who is a doctor. He said that invariably the one thing all men lie about is their height. According to him, men usually add two inches."
I don't see how anyone thinks they can verbally add 2 full inches to their height and not have the person they are lying to immediately think, "yeah, right." Not saying it doesn't happen...but it's dopey.
I think this is interesting, though: a good friend of mine who is 6' plus once asked me how tall I was. I told him, "I don't know, about 5 foot 9.5 inches." He laughed, and asked me if I ever noticed how guys 6' or over will usually give their height in a round number, to the nearest inch, while guys under 6' will invariable add whatever fraction of an inch they can reasonably muster.
I've tested this on occasion and found it to be almost 100% accurate. Excepting this forum, perhaps, and in sporting stats, the average guy on the street doesn't say he six-foot-two-and-a-half inches; he says 6-2. Guys in my range though always add the fraction.
