Too cool indeed. At least in the cold sort of form. I use a laptop and at the moment I have been keeping my hands under the warm laptop just to keep my knuckles from freezing off. :) I'm notorious for having cold, cold hands in my class. I've been caught wearing gloves and mittens several times by kids, and in fact one boy laughed out loud and told me he would pay to see me try and eat while wearing them. Can't say I didn't laugh at that.
My doctor suggested I get a wax machine so I'll keep my hands warmer and probably prevent damage, but for right now soaking them in warm (and then hot) water with the nicest handsoap we have every hour or two is helping, as is wearing gloves and sitting on my hands. :)
What do you do to keep your fingers nice and warm during cold weather?
