As a teenager just out of high school I was riding a borrowed old 10-speed racer home from a summer job when I got caught in a downpour. The brakes were useless (chrome steel rims) and I had to turn after going down a small hill. The front wheel caught something and the bike slid out from under me. I was just a little banged up (mostly scraped up pants) - I didn't hit anything but the road. But it made me appreciate how quickly things can go very badly wrong on two wheels.
I'm sorry you were injured, but glad it wasn't worse! Heal quickly!
Cheers,
Scott.
