i've been in a lot of car accidents as passenger and i never wear a seatbelt, some have been bad ending up with car on its side and totally wrecked, but i have never been hurt.
i was once flying down the highway on my bike last year, at about 160 mph , i was trying to see how fast i could go (as you do) and someone pulled out on me, i came within inches of me hitting them at that speed, so i guess i would have been dead, it was one of those adrenaline rushes.
then there was this time a herd of cows chased me, ha ha ha
another thing which was this year when i was in africa i was out in the ocean in a bit of a sharky area, and i saw fins, i didn't know what to do, then as they came closer there were more, i realised they were dolphins, about 40 of them they came right by me and all sides, that was quite unnnerving because they are big up close.
i'm sure i have been near death through lack of sleep too, one time i didn't sleep for a long time and was so messed up that i started hallucinating and seeing the basil rathbone sherlock holmes standing in the doorway, that was when i knew i needed to sleep, i also remember having total memory loss that night, it was like amnesia and like my brain could not absorb anything, did not know who i was or where i was, this was more scary than anything because i did not know if it was really happening, it was bad, in the morning when i woke up i had to ask the girl i was with if i had really been that gone, and i had, that scared me more than anything else.
