How to protect myself when falling off the bicycle Today was rainy in Palo Alto and I was driving home in bike lane. My bike slipped and I felt off my bike in a part of bike lane that was made of concrete instead of asphalt(here). I didn't injured and I am fine.

When I was falling down I didn't know how to shape my body to protect myself and prevent serious injuries. What should I do in situations like this?
I suggest following a short course in some martial arts class where you can learn to fall correctly (Judo would be my suggestion)

there is nothing you can read that will prepare you for a fall and that will suppress the reflex to stick out your arm to catch yourself (and possibly break it); only practice will have you instead tuck in that arm provide a convex surface to the ground and roll it out
