You could say the same thing about driving a car. How many people have never been in a car accident of any kind? Probably not very many. "There are two kinds of drivers: those who have been in a wreck and those who will be..." Blah, blah...
I've wondered why this old spiel started and exactly what the point of it is.
I figure it either developed as a kind of "bravado" statement, like "I ride a motorcycle and it's dangerous so I'm a bad-ass" or maybe it's just a kind of a friendly reminder that the roads are dangerous and to be as careful as you can. I would like to think it's the second, but from the way most people say it, it seems to be the first.
Hope all my tip-overs, dumps and spills from being a piss-poor off-road rider count for my quota as far as the roads go, too.
Plus, I never know exactly what they mean by "going down." Dumb-ass parking lot tipover? Trip to the ER? Fatality accident?
Let me put it this way: I never say it, not because I'm afraid I'll jinx myself or somebody else, but because I think it just doesn't make any sense and sounds lame. I do, however, use lines like "Remember, ride like everybody out there is trying to kill you" and "Ride like you're invisible." Those two things I do believe.
