Cold; does it cause laziness?

I haven't written in a while due to a severe lack of motivation. It is mucheasier to just get off of work and lay in bed than to entice thoughts and put them into words. It has been between -50 to -60 degrees (including windchill) so about -35 or so ambient. That in itself causes me to be unmotivated. Luckily I go home on Wednesday for a couple of weeks to get out of these frigid temperatures. Hopefully I will get a little more time to write in the next few weeks. Everyone have a good Thanksgiving.
