 I assume there are some who are saying, hey, suck it up. It was hot for all of us when we were in school, but are we just paying more attention to it these days? I would say the heat is becoming worse more than paying more attention to it. I think there's a lot of parts of the U.S. where A.C. was not once a requirement for a building or for a home or things like that, and the changing climate means that it now is.
