I wonder if this is a women thing, but I go to my sister house, and I have been at others houses run by female. They all turn the AC on at nite during the winter time. Why are they racing to make the house cold at nite, when nature outside will make the house cold all naturally? Then at 8am in the morning they turn the heat on full blast. To me its like shock treatment.
Because men, generally speaking, have a larger body mass than women, will not have the same feeling of temperature of women. Ever notice how at an office, while the guys are wearing short sleeve shirts, the women are wearing sweaters? Or at least I've noticed that while living in Texas, Nevada, Florida and other hot/warm states.
