Whenever I ride trails and anything that I feel I could hurt myself doing, but not every time I ride a bike. Like I live two blocks from where I work and it's just sidewalks so I don't wear a helmet when I ride to work.
This was like a week after I landed on my head trying to pedal off a concrete ledge and my chain slipped. So I landed on my face, I wasn't wearing a helmet. I do now... most of the time.
blacked out, then morphine. don't remember it at all. they gave me pills and i didn't even need them. i was only in the hospital for about 4 hours so it wasn't too bad.
