I'm still slightly under the weather. As I was walking to my 2 hour class today, psyching myself up to appear energized, I thought about how much energy it takes to enact "professor" in a classroom, and how absolutely vital it is to try to put forward the energy. I don't think teaching and learning are all my responsibility in a classroom, but I think my trying to enact "professor" with good energy makes a difference. And is difficult sometimes.
I've gotten hardly any exercise while I've been feeling under the weather, so finally, Sunday, I rode my bike on the trainer for half an hour. It was fine, and I feel better for it, but I can't imagine trying to compete in any sort of real way while feeling under the weather. I can fake my way through teaching a bit, but I couldn't fake my way on a bike at all.
