Agreed! I've only fallen once on ice and it's unbelieveable how quickly one goes down. I, as well, had no time to even think about putting an arm or leg out (probably just as well) and hit the ground in riding position. You were booking along, it seems; I was creeping and still didn't have a chance!
I hope you heal quickly, ribs are really painful. That whole breathing thing is tough, not to mention a cough!
I'm done until the roads clear. I'll purchase studded tires this Summer for the coming Winter next year. It seems too late now, and my cycling budget has been allotted to a Summer only road bike restoration. Perhaps the revamped road bike will be the basis of an indoor trainer during the Winter.
Feel better soon.
