I shouldn't have broken anything on that fall. Apart from being too old to hit the pavement at that speed, I've lapsed in my training for falls and rolls, and neglected upper body work which might have cushioned it some. It was completely avoidable and I was careless when looking back in the first place. To me it's a wake-up call: don't only bike and neglect other physical training.

On the bright side, my helmet never hit the ground and no other damage occurred.
