When I worked in an office, I was always either really hot or really cold. People were constantly changing the temperature. It should just be left at a certain temperature (according to the season, maybe, but, not according to each individual). I would always just layer. I remember a few times stripping down to the least amount of clothes that was acceptable and then an hour later have four layers on. It was so stupid. They wondered all the time why so many people got sick. Duh.
