I know this sounds a little trivial, but thought I'd share this anyway...
I got knocked off my bike earlier this week, and dislocated my shoulder (you know that sound when you pull a chicken drumstick out of it's socket? I heard that come from my arm ). All has worked out well, but a few things worried me at the time. I normally carry a slip of paper in my wallet with "In case of emergency" numbers... well, it was there, but had all my OLD contacts, didn't it. Also, even though I was only 2 minutes walk from my wife's work, I could not get in touch with her, cos my mobile was with my bike, and I did not know the business number (and the ambo officers and cops could not understand my mumbling of the business name in either english or cantonese).
sooo, even though it is common sense, probably worth making sure you have some numbers scribbled someplace before you go out and get smashed, fall under a bus or get swiped by a green top on the way home
