I'm apparently doing something wrong...I don't remember ever having a near-death experience. Maybe mine was just so much more traumatic or unlucky than any of you guys' and amnesia/denial has blocked out that incident.
Yeah, I'll go with that...
Well, there were a couple of times.
My friends and I used to love going out into the local forest and try deliberately to get lost and find our way back, trekking through treacherous mountains (big rocks), thundering rivers (streams). It was mostly fun until, during the winter, a snowstorm hit. Cold and really lost, we winded up on the wrong exit out of the woods (granted, it was still suburbs). We trudged through a fucked-up blizzard and me and my best friend fainted a couple of time.
Another time, during the winter, we were sledding down one of the local hills when our sled flipped over a bump and sent us flying through the air and lying in the snow at the bottom of the hill. Just I was about to get up, an inflatable carrying at least three people ran over me, effectively flattening me into the ground.
Neither of these were really life-threatening (especially the second one), but they're as close as I can be.
