Broke my ankle when i was about 11 playing a massed game of chase and slipping on wet grass.
Broke my right wrist playfighting with a bloke.
Broke my left wrist falling off a gate at 4am
Knocked myself out tripping over god knows what.
Numerous falls off horses, bikes, out of trees, off haystacks and sledging (the best hill where i grew up has a big wall at the bottom

)
