one day last year I was in the gym and went to the lat pulldown machine in the middle of my workout. someone had it on 200 lbs or something, so I pulled the pin out of the weight stack, and the entire attachment fell on the back of my head. this was a really heavy metal attachment, must have been like 20-30 lbs fell on my head. I got really dizzy for ~30 seconds and had a big bump on my head, but that was somehow all that happened.
to this day, I'm kind of scared and cautious whenever I change the weight on those machines.
Tried to walk across a small frozen stream in the middle of the woods when I was like 8-10 years old, fell through and got sucked into the mud.
Thankfully my cousin was there to pull me out but it took like 5ish minutes to fully get me out. Both of my boots were stuck in the mud and came off my feet as I was pulled out.
We then had to walk back to my cousins house, which was like 20 minutes of walking away, through the woods in like a foot of snow. By the time we made it back I was verging on frostbite. So maybe not fully near death but definitely bad.
