So here's the thing. I have lived most of my life in humid places where 100 is torture. I've also been in the west in very dry places where 105 is quite pleasant, 110 is starting to push it, and 115 is challenging and you definitely want water with you at all times, and yet it is not at all that gross discomfort of humidity.
I've always wondered, what happens when you get to 120? Or 125? Does your body start doing weird sh-t? Do you just dry out so fast you need to wear those kegs hats only with water in them? Does it hurt?
So, what is the hottest you have ever been out in (not in an AC car) for at least 5 minutes? And what is that like?
Also, when I was in 115 in AZ you could not have paid me to drink -- the thought of alcohol would have been enough to give me get a heroin addict's cold shakes. I completely get why desert people stay away from alcohol -- it's why the Jews stayed away from pre-refrigeration pork. It's a trip to the emergency room before there were emergency rooms.
