About twenty years too long.How long have you been in AZ? I know when I moved here as a broke college kid I felt that way a lot in the summer. I could beat the heat and moist swamp cooler by doing as much of my studies as I could at libraries and food courts. If you can get out and about in the summer it helps while your bodies learning to adjust to the heat. It took me years but I'm finally comfortable in AZ summer weather... you'll get there too!
The real problem is the desert has ruined my lungs and eyes. Doctors keep telling me to move back to the coast. I'd like to know how to afford that... Also, one of the reasons I left home was because of the Northridge quake. I lived through a horrific experience I don't like to talk about. It was a nightmare and I never want to go through that again. I generally try to stay out of earthquake areas.
One of the things I like about living here is that it's geologically stable. I can go to sleep at night and be reasonably certain that the walls and ceiling will still be in the same place when I wake up!
