Ok, I got a few.
First off: Skating. NOT beneficial to your health.
Incident 1:
I was skating on this horrendous skateboard made of metal that my friend made me. I decided to skate down a hill with a 15% incline. In the industrial district. I decided to ollie on that hill. My trucks were so loose that the wheels touched them. Needless to say, I failed. Hard.
So I flew about 3 meters, onto my elbow. Like, the flat of my elbow, on the inside where tendons and shit are. Onto a freaking Industrial sized bolt that they put in furniture. So, the bolt went half into my arm, about...half an inch deep, and basically cookie-cutting a slab out of my elbow that was about an inch in diameter and half and inch deep. Strange white strands were showing. Figured out they were tendons later.
Not the worst of it, however.
Immediately after seeing this clean crater in my arm caused by a nine inch bolt lying in the middle of the road, my brain screamed 'TETANUS!'
So at this point, my friend had spotted me from the bottom of this hill and was riding up on his bike to the point where I was. (The road on the hill is about 100m long) So I freaked out and ran to a tap at the other side of the road, behind a building. Keep in mind, all I was thinking about was tetanus, so I poured water directly into this hole in my arm. I literally hopped up and down on the balls of my feet immediately, swearing my fucking head off.
My friend laughed his head off.
On top of this shit:
I went home (walked), showed mum this hole in my arm and asked politely to go to the hospital. She said it wasn't necessary (there was a clean 1 inch hole in my elbow, tendons showing) and that I should wash it and put a bandaid on it. Surprisingly, my mum is not a druggie, though with this recommendation, you'd think she was.
Not the only bad skating injury I've had, I've got some bad permanant shit from it. That hole healed up in about a month and it just looks like I just stuck my elbow on a superheated bottle cap now.
Another time, I was at the skatepark and I decided to try the quarterpipe, for my first time. So I rocketed up to it, launched, and came down. Turned horizontally. I put my left arm out to cushion the fall. Considering I'd just flown one and a half meters above the lip of the pipe, not a good idea. I came down really fucking hard on my wrist, which literally jammed. Locked up. Couldn't twist it at all.
So I called mum, and she arrived as usual.
"Hospital please, mum."
"Put ice on it"
So I did, and since then my wrist will not turn smoothly at all. It gets halfway round, jams for a second, and then turns. Does that EVERY time I twist it.
It's calcified now, so no hope of ever fixing it.
The only reason I've never broken one bone, I think, is because I ONLY drink milk. Nothing else. Ever.
Anyway /rant.
