Well you can’t live without heat in MN and you can’t live without air conditioning in AZ.
Electricity ain’t cheap, unless you are well off, most middle class can’t cool to 72 in the summer in AZ.
Gee, I’m sure I’ve read about towns thriving in Arizona long before electricity, and/or air conditioning. It’s surprising that it wasn’t too hot for the “gunfight at the OK corral”.
I’m sure MN was well acquainted with firewood, coal, etc., back then as well.
Like I said, I grew up without Air Conditioning, finally got a window unit installed after I was married, at age 25. It only cooled the room it was in.
I’m saying that people will survive in what they are used to...thus the point of my whole post, and the contrast between being inside with a/c, and going outside, is the point...like going into a darkened movie theater in the middle of the day...you eventually get used to it.
I still live in Georgia, with central air conditioning, but in the summer we spend a great deal of our time sitting out on the screened porch, or barbecuing on the patio.
I remember, as a kid, people from up north coming down here and having to be in the Georgia heat...like sales people, etc., they didn’t last long, and would soon return back to their northern homes.
There are no absolutes.
Heck, with 12% humidity in the Phoenix Valley 72 wouldn’t even be comfortable. We go in and out some during the day, so at our house in the Phoenix Valley we have the thermostat at 78 degrees. If that feels too warm, we turn on a ceiling fan and drink some ice water.
