questions of an accident

so, nobody freak out, but yes, i did get hit by a car as i was biking home tuesday evening. I'm fine, i just have some road rash and soreness, and i went back to school friday. but it got me wondering (as i am prone to do) about what was going through my mind as i was getting hit. obviously there was probably an adrenaline rush, and yes, time did seem to slow a bit as the car was coming toward me, a documented incident caused by the brains vivid remembering of details in a life or death situation. other than that and my wanting to cuss the guy out after it was over, that's all i know. sorry, but it's not like i have a phd or anything. maybe you know someone who does. and that's what i really want you guys to get from these posts, not answers, but questions that you can go out into the world and answer for yourself. just please, please please don't answer this question: "what's the worst that could possibly happen if i don't wear a helmet?" cause the answer will probably suck.
