I worry a lot about getting injured (and ruining my season) so I don't do things like ski (Ian Charles and Lara Brown injured) or mtn. bike (I've put myself off a cliff while racing). So I try to be careful and even commute in the city where I see a minimum number of cars - I even descend pretty conservatively.
I get to work this morning, climb off my bike and proceed to unlock the office door. My bike then falls on me (it was leaning again me) - leaving a massive cut and golf ball sized bruise on my knee and shin.
At least I didn't lose a tooth and I don't live in the Gaza Strip - so I shouldn't complain.
