I'm feeling pretty bad about myself tonight.

My husband seems to think that I have hot spells because I've become about 20 pounds overweight in this past year.
Today, as we were riding in the car, I told him I was sweating and too warm. He reluctantly turned on some air and said, "you need to start gagging yourself after you eat".
I told him doing that was a serious illness.
I also told him he was a mean S.O.B. and didn't talk to him the rest of the way. Does being overweight make you warmer than other people?
