I got a concussion once while riding a three wheeler as a teenager. There was a large partially downed oak tree that I used to duck and ride under probably hundreds of times. To this day I don't know if I just didn't duck enough, or whether it dropped on me. Anyway, wham! All I recall was a loud bang in my helmet. No pain or anything. Somehow I slowly rode back to my house and when I got home, I discovered nobody was there! I guess I made the decision to call 911 myself. I remember the ambulance coming and then I blacked out for probably the next 12 hours. I do not remember the hospital at all to this day. My next memory was my mother waking me up a few times at night. I was exhausted the next day and spent the next three in a bit of a fog. My mom is convinced my math skills started to suffer after that accident.
