It got above 30 this morning, so I wrapped up and went for a short ride. I rode reasonably well (for me) and was warm enough. When I finished, I put on a jacket, turned on the heat in the car, came home and jumped in a hot shower. Then I put on long johns, a shirt, another shirt, and sweat pants. I ate a hot lunch.
And when I sat down to grade in the heated house in front of my little space heater, within about ten minutes, I was shivering. Blah. It's hard to focus on grading when you're shivering.
I don't know why I'm so cold. I don't think I'm getting sick (I biked and felt good and rode reasonably well for me and I don't think I would have felt good and ridden that well if I were sick). And I don't feel sick.
I don't know how to face being cold for the next six months.
