for almost 30 years the wife and I have been opposites. If she's hot, I'm cold, etc. I worked for 9 years in hot kitchens, then 20 years in an even hotter factory. I'm fine on a 90 degree day with just the fan in the window after 8-12 hours in a 110+ factory. She wants the air on if the t stat shows 72. We have no register in our bedroom, so it get pretty cold in the winter when it's cold outside. That's fine, I like a cold room to sleep in, but I want the electric blanket on. SHe'd have the windows open (and has) when there's snow on the ground.
