(I know this post is partly or entirely a joke, don’t at me) This would be very difficult. There aren’t just “bearded” men and “beardless” men. I usually grow a beard a winter and keep it clean shaven or just stubble in the summer. When I shave my beard, do I lose or gain those measurable differences between bearded and beardless men? Obviously the measurable differences between the women could be studied, but hopefully my wife is attracted to me in both cases 😂
