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.
When I was a child, my mother decided to take me and my brother canoeing. It was chill at first, but then the dam upstream released some water or something and the current picked up. We came to a fork in the river and my mom wasn't sure which way to go and we chose the wrong way - a part of the stream filled with trees and a drop at the end.
My mom thinks I got knocked out of the canoe by one of the trees, but I actually just jumped out and held on to the canoe cause I was scared. Lost my grip on the canoe and somehow got pinned to a tree by the current while underwater. The river was too deep for me to stand on the bottom, I was just stuck and kind of drowning. Only reason I got out is cause my mom grabbed me while she was floating past, I think she also jumped out at some point. Managed to make it past the drop as well, it wasn't as steep as it seemed. Stayed away from rapids for most of my life after that lol.
