I was sitting at my computer in the basement on NS reading through the forums. I haven't put a rug down yet because we just remodeled, so my feet were very cold. I got up to go take a piss and I noticed that my right little toe felt weird. I took off my sock and saw that it was white, numb, and frozen. I had to sit in front of a space heater for 15 mins to warm it up. So don't let your toes freeze while you're on NS.
