Guys are gross. It’s not a question. Civilization has meant some compromise in the best interests of living together in closer and closer quarters and all, but our true, animal nature comes out whenever the circumstances are right. That’s not a comment on personal style in any form. An individual guy can be messy or a neat freak; he can be meticulously dressed every day or a slob through and through. All of that is just what you see on the surface.
