Every guy lies about there height. I'm exactly 5' 9.5" (176.5cm for metric losers) and most people my height claim to be 5ft 11in. I'm a man of science, and this bothers me to an irrationally extent. I'd estimate 80% of American men add an inch or more to their height when asked, and I've NEVER met a person that gave their height to the precise half inch. Have any scientific studies been done to show how much men lie about their height on average? I think this would be a really fascinating study.
