Every office full of women that I've worked in has been a refrigerator, as the post-menopausal ones were loudest about the thermostat. The really cold one had no men at all.

I love AC, but someplaces are even too cool for me. My ex keeps her thermostat turned down to 71 all summer. Mine is at 76/78. Just one of our marriage issues! In winter it had to be turned to 80. I keep mine around 68, 56 at night (That's what blankets are for! Seldom actually drops that low and feels great in the morning when it's heating back up.)
