I got hypothermia once when skiing in Utah. I was in jeans and they got sopping wet. As soon as I ended my runs, I started shivering absolutely uncontrollably. There was no way to stop that involuntary violent shivering.
Fortunately, my car was only a quarter mile away (but I wasn’t even sure I could make it that far).
While obviously not life-threatening in the parking lot, it gave me a super appreciation for hypothermia in the wilds. It took a long soak in a hot tub to get over that.
Yeah, I got to the violent shivers once. Cotton kills.
