I went dirt-jumping with my friend, didn't check out the jump before i went over it, and didn't attack the jump enough. Turns out it was a gap jump, and I didn't clear it. Anyways, wasn't wearing a helmet because I was stupid, flew over the bars. Other than a nasty gash in my head/mild concussion (the doctor didn't say I had one, but I lost memory, so I think he is stupid), and some bad scrapes, I was alright. Didn't break anything, but I think my muscles absorbed most of the impact. I've been sore for the past three days.
Now the question is: since I wasn't wearing a helmet, did I have anything in there worth protecting? It's a catch-22.
