" Ignorance of the actual dynamics of daily life can be bliss sometimes. Because we know chemistry and biology, we know that when we smelled something, the molecules from the source of the smell had actually entered our noses and taken up residence on our receptors. So when we smelled a dirty person, this meant that some of his filthy molecules had actually gotten into our nasal passages. This bothered us. We didn't want to know that person that well, and we certainly didn't want his disgusting molecules in our nasal receptors. "
