I have learned that someone else turns the pillow and finds the underside cooler. I had thought it was my private invention. Why do you think we do that? Do we heat the topside with our heads? The head seems to function as a giant radiator. Mine does. How, do you suppose, we discovered the underside of the pillow? and come to use it in our sleep to cool off? Did we slide our hand under there one warm evening and find to our delight that it was cool? Were we trying to get the pillow to fit us better?
