It's air conditioning. When I was a kid, we had a window unit in the living room and didn't have it in the rest of the house. Now we live in AC, work in AC, shop in AC and drive in AC.We've had a couple over 100 so far but really hasn't been too bad.
Every year it gets harder and harder out in the high heat. 1st year in 30 I haven't been in it all day everyday. Getting hurt sucked but it is nice not getting so hot and dirty every fucking day. I hate office work though so.....
