I must be really different to most other people then, cause when I get hurt I just screan loudly, get up and start riding again. Like I slipped off the pedals once (gusset prosecutors) and took a couple of huge chunks off my shin (biggest was about 10cm long 1cm wide and 1cm deep). I screamed, got up laughing and tried the thing again. When I screamed, someone ran over and asked if I wanted an ambulance and my freind just said 'no he does this all the time' which made me laugh. I ended up going to the hospital anyone as bits of the hole were white and were not bleeding which a lot of other people thought might be bone. Ironic ha?
