I wouldn't call these near death, but oh well, still painful nonetheless.
When I was younger, I got both Appendicitis, and Lyme Disease (separate times), and had to go to the hospital both times. With the Appendicitis one, my mother though I was faking, and didn't realize until I couldn't walk, that it was in fact real.
One time, I had my head out of the window of my dad's car, and he, not knowing that, rolled up the window on my neck.
Another time I was bogey boarding, and the wave pulled me under and I banged the back of my neck, and got a mouthful of salt water, although, I was luckily sent to the shore by the same wave.
And most recently (last August) I fell down three or four rows of seats at the Georgia Dome because my friend's family didn't give me enough room to walk, and I was in a hurry to see one of my favorite drum corps perform.
this one isn't about me, but there was that time my friend fell out of a tree and fractured his spine. And the other time we accidentally dropped a heavy rock onto his leg.
