Aerodynamicity

Haircuts threw off a ballplayer's equilibrium, because they subtly altered the weight and aerodynamicity of his head.

Look, I get that aerodynamicity is a prerequisite for superhero uniforms. But consider this: Superman: chin to toe coverage. Batman: head to toe coverage. Spiderman:^([sic]) face to toe coverage. And not one of them is photosensitive.

It has been speculated that this is the effect of an evolutionary adaptation to the environment, preventing the formation of biofilms that affect the aerodynamicity of such insects [24,26–28].
