I have horrible bones/coordination and grew up somewhere very icy, so I slipped on the ice and bruised my tailbone or knocked my spine out of alignment 7 WINTERS IN A ROW
I also had horrible cold urticaria, which meant for most of the winter (where it could get to -30 F) I was a grumpy puff of hives.
I think my favorite winter moment was this: because of said bad bones and coordination, I hated downhill skiing. I would fall between my skis and end up speeding down the hill on my slippery, snow-suited butt, unable to break free, shedding skis and poles behind me. One time I did this on some black-diamond moguls and was flying off moguls on my ass, only stopping when my head hit a tree. Shockingly, I started refusing to go skiing.
Being from a ski family, this meant cross country skiing instead, but downhills on cross country are even worse because the skis don't wedge well. Our cross country loop had a part where you just put you skis parallel and sped down, and it terrified tiny me. For the whole... must have been at least 100 feet, I would wedge in my poles and scoot down as slowly as I could, and still managed to fall every time.
Finally, for the first time ever, I made it all the way down without falling. I raised my arms in the air, shouted "I did it!", overbalanced, flew over the front of my skis and face planted in the snow.
