Lenusik- I feel for you! I grew up in Yuma, and remember all too well the killer heat we used to have. Somehow, the body sorta adapts. When I went back 12 years ago I thought I would die when it was 115. Yikes! I guess your body adapts to where you live, because 100 degrees now kills me here.
I also remember the good part about living in AZ- like never having a real winter and using a windbreaker during the coldest part of the year. My world fell apart when I moved away and had to buy a bulky winter coat and felt temperatures below 40 degrees.
