Me? 79 degrees. Plus, I turn my Air Conditioner off when I go to work. People think I'm crazy but I am not used to cold air because I grew up with no Air Conditioning. I've noticed that people who set their A/C on below 75 degrees tend to whine about the heat the most. We can put the man on the moon but we can't find an ultra-efficient method of cooling that is just as effective as the refrigeration cycle.
