So, in the interests of science (and not because I'm a lazy sl*t perish the thought) I haven't shaved my legs and can report . . . I'd say the outside faces were less hairy than the inside ones.
All you need now is a randomised control sample of Pw/oP, assign trial numbers randomly, collect the response blindly - and you're in for a research grant!
PS, do make sure no owls take part, they could seriously damage the integrity of your data, what with all those feathers.
