It depends on the type of crash and, the extent of 'shock', that you may have suffered as a result. Back on 09-30-04, I was about to cross a railroad track. This particular track was not 'hugged', by the asphalt. There were gaps on both sides of each rail, wide enough for my tire to slip into. I, stupidly, got my wheel parallel, instead of perpendicular to the track. It sent me over the handlebars. I bruised a muscle in my chest and, it didn't stop hurting till last week. I still rode my bike.
