I took a walk in the evening after finishing up work, which is worth mentioning only because the temperature was oh-hell-no degrees below freezing but I needed to get out of the house. Besides, I still have the parka the Air Force issued to me when I was stationed at Misawa, at the northern tip of the Japanese main island, not that the winters in Misawa are cold enough that anyone would need a parka designed to keep them warm during an arctic winter, but I was grateful for it nonetheless. After I dressed up in layer after layer of clothing, I zipped my parka all the way up so you would not have been able to see my face unless I looked directly at you, and even then all that would have been visible would be my nose and eyes. It’s one of those parkas with a hood like a snorkel with a white furry fringe around the opening. The furry fringe keeps the wind out and the snorkel traps a warm cushion of air against your face, which would be great unless, like me, you wear glasses. The snorkel doesn’t keep the air warm enough to keep my glasses from cooling off and thus fogging over. I had to fiddle with the zipper a bit until I got just enough ventilation to blow away my breath but not so much ventilation that it defeated the purpose of the furry snorkel. Hard enough to see out of that hood without foggy glasses.
