I like the fact you've had so many "crashes" that you can base you views on, but I expect in most if not all of them you were able to reduce your speed before you came off...chances are that's the only reason your "still alive"
Oh, you like that, it pleases you does it? At least I'm talking about things from the perspective of experience, not sanctimony. And no, you're way off the mark about being able to reduce speed before crashing - were that possible, the crash would be avoided - not possible when racing I'm afraid, crashes tend not to give an awful lot of warning before they happen, even on the road. The reason that I'm still alive is down to primarily two factors factors;- doing it where it's safe (ie. racetracks, or open roads away from traffic, junctions, road furniture, people etc.), and wearing the proper gear.
By the way, if you're going to be high and mighty, learn to puntuate properly; "your" is a possessive, "you're" is an abbreviation of "you are", which I believe is what you're trying to convey.
