I've spent a good deal of time in Yuma when it was over 120 degrees. And while it was very warm, rather than hot, and I was wearing gloves, I have touched a critical nuclear reactor... As in, I was in the reactor compartment, the reactor was at minimal, and I was fixing an essential alarm circuit - while underway. Lost a chevron for that... Senior Chief was not at all impressed with my opportunism. Also received two years of exposure, according to my dosimeter. Worth it for the story that goes along with it. Losing a grade sucked tho.

I sometimes work with objects frozen in liquid nitrogen. I've accidentally touched a sliver of bare skin to the inside of a cryogenic storage tank. Almost -200 degrees C. Burned like a motherfucker.

walking to work in sneakers, jeans, dungaree jacket in february at -35 with a 20mph wind. It was brisk to say the least as in my dick felt like it was going to fall off if it got any colder and that metal fly felt like wire that was cold enough to almost stick to skin. Now on around summer of 1990 it was over a 100F for 3 weeks never below 90 even at night. Well I had no tv not radio no clue. Living on a 3rd floor attic room in a rooming house "I drank a lot more than I wish I did".

I found out on the first day of 100F, I worked 2nd shift till 11pm then walked home where my cooler and 12 pack in it were waiting. Drunk in short time then to bed. Got wokened by loud machinery noise. Looked out to the main road to see and asphalt grinder removing the road 50 ft away, like a jet aircraft with louder bangs at that distance. I did not sleep maybe 125F or higher in room no fan and 2 small windows facing the road and heat and machinery, she's to cheap to pay for our luxeries, but I did drink my ass off all day before work, my supervisor drank vodka at work, good friend so I was cool to run the machines feeling good.

Just to get it summerized maybe 130F during the hell. Then the weekend hit. So I was hot for 3 days getting 2 hrs sleep in that 75hr stretch and drinking and toking a lot more than normal since daytime was sleeptime but no sleep must be time to drink drink drink. It was an interesting time back then that is for sure.

Hottest: 128°F near Needles, CA. We were camping on the Colorado River and it was still 114°F at 2:00am.

Coldest: -42°F in Cheyenne

For my part, I've been out desert hiking when it's climbed to approx. 110°F or more (no nearby weather stations). I've been camping in a tent at -14°F I think.

I have touched the bad part of a soldering iron, gotten my thumb cut & cauterized by a cutoff wheel, and for cold, the liquid nitrogen.

Hottest: Dropped a fry basket fresh from the oil vat onto my arm. It actually didn't really hurt much and the blister just scabbed over and fell off in a week and then was fine. Maybe it was a Leidenfrost effect thing with the moisture on my arm, not sure.

Burned the fuck out of myself on an oven at 500 F. I've also accidentally dripped a bunch of liquid nitrogen on my skin and hands. Hottest weather was something in the 110s in Florida and coldest was - 10 in Chicago.

-40 on the low end 112ish on the high end (maybe about 130 on the high side if you count getting into a hot black car on the 112 plus day)
