Sometimes I think I should skip teaching summer classes because I sweat so much that I worry about my students! At one school especially, I move around the room a lot and hunker down next to one student after another. I'm very self-conscious about any possible odor.
Everybody smells like something if you get close enough to them and have a keen enough nose. But I would rather smell like nothing at all. In the warmer months, I wish I could wrap myself up in a body-hugging force field from, say, May first to November first.
