Here is an academic paper that examines, and finds a positive statistical correlation, between average penis length in a country and its economic performance.
Apparently the economically optimal penis length is 13.5cm. That's less than 5 1/2 inches. Makes you wonder, doesn't it? Of course, that's for a population, not for any one individual!!
Must be real tough to find good subjects for tenure-aimed publications these days.

Come to think of it, I'd like to know how they ascertained average penis length in the first place.
