If you're anything like me it could have been any number of quite innocent activities - from getting it burnt on a hot water bottle (despite protective covering), to flinging the arm out of bed and bashing it on bedside furniture, to having it go wrong when merely trying to lever oneself out of bed.

I've never tried to count injury-free days but, given how extraordinarily easily I get damaged when other people wouldn't, I probably can't make it to 1 day - perhaps not even if I was allowed a freebie injury each day that didn't count. I basically start off damaged and things only ever go downhill from there.
