A friend of mine, who just so happens to be a girl, asked me if this statistic was true. I replied:
Well, it's not technically true. We don't think:
food-food-food-food-food-food-sex-math-math-math-math-math-math-
sex-e2-e2-e2-e2-e2-e2-sex
It's more like:
food-food-math-math-e2-e2-...60 minutes...-ASCII Porn-ASCII Porn-ASCII Porn-....10 minutes...Lather, Rinse, Repeat
The important words is average. If we apply the distributive property, we get: The Average Male Thinks About Sex, on Average, Every Seven Seconds. A similar truism is "The Average Human Sleeps Every Third Second". Even though we don't work-work-sleep, we do work-work-...16 Hours...-sleep-sleep-...8 Hours.
So even though 68% of Statistics are madeup, and the seven seconds part of this one is probably an urban legend, it is true...if we use mathematical logic on standard english.
