I like the cold. I really, really do. But I shoveled the driveway, then went for a half hour walk. Later, I went for a longer walk with R. Towards the end of that walk, I realized my back hurt, probably from shoveling and sweeping snow (a few times lately). So I took a couple aspirin, had a blondie and crawled under the new electric throw. And could not for the life of me get warm. I gave it a good shot -- all the way through a Sam Smith album on the Pioneer AirPlay speaker -- and then made dinner and had a glass of sake.
Miraculously, I am now warm. Go figure. Food matters.
