Could you put a small electric coffe percolator close to your computer? The steam from heating the water may moisten the air somewhat while you're posting. The alternatives are more hours at the steamy burger joint or taking showers with Richard.
Actually, the steam at the burger place is probably what's kept me from getting bronchitis so far this winter!
My coffee maker is small and doesn't make much steam, but I suppose I could try it. I'll see what happens tonight,
with the heat turned down. If all else fails, I'll shower, but I'm not flying to Flagstaff to do it!
