Haven't had a near death experience, just a few close calls like most people. The closest was probably getting hit by a truck (the big ones) while on bike. I was going straight, he didn't see me and turned right, hitting my bike and sending me flying out on the other lane, where the other cars thankfully stopped.

No injuries though, just the bike, and that was my friend's (he was with me at the time), and he got that covered.
Two years ago, my brother was really close though. While playing Test Drive Unlimited (which he only played cause I had told him to try it), he was hit in the face with a 9mm bullet from ~100m away. Some idiot playing around with a gun apparently. The lucky thing was that the bullet had lost speed over that distance, and went through a window and into his right nostril from the side, and stopping an inch or so under his eye, slowed by the bone. Now if he hadn't played that damn game, he would not have had a steeringwheel between him and the table, and therefore sitting a bit closer. In that case the bullet would most likely have hit the side of his head and sent itself and/or bone fragments into his brain. Now he doesn't even have a scar.
In China, around 10 years ago, my girlfriend would have fallen to her death if not for she and her mom seeing a huge, odd buddha figure that they just had to see up close. When they got over to it, the light from that side of the road showed that a series of deathtraps consisting of open drains littered over the dark road, and one in particular had been extremely close to ending their lives.
Also, her brother almost died of kidney failure and subsequent bloodpoisoning of being treated nearly too late. He was 18 at the time, he is ~31 now and only got a new kidney last year. It was due to a shitty malaria-vaccine they got, my gf got exema (sp?) and her mother psoriasis.
