This is almost comical to me. I used to roadrace motorcycles professionally. Now, I didn't take risks; I was very conservative and very smart. I prepared my body, my mind, and my machinery. I would walk the track, looking at the camber, crown, etc., then during the practice sessions, I would try different race lines to see how I got the quickest time, best acceleration out of the corner, etc.
By being careful, the best I ever finished was 5th place, with a few top 10's, but most importantly, I finished every single race I ever started. I scored enough points that although people would beat me in individual races that they would take risks to try to win the next one and crash. Once, I even made the ESPN crash of the week because I was the only rider in a group of about 10 guys who remained upright through a pretty terrific crash. (I did crash once at Talladega while passing a Harley, but I dropped it in such a way that I was able to get back up and on the track and only lost two places and passed the Harley a couple of laps later.)
But, I scored points in every race, and in so doing, I was invited to the championship race, while those who beat me in individual races did not.
My point? During all of this, I was never seriously injured. But, while walking out the door at work, I slipped and fell and broke my ankle in four places, ripped all the cartilege and ligaments loose, had to have 4 surgeries, have a permanent steel plate, 8 screws, and two pins.
Life is full of risks, and we can't (nor should we) avoid them all.
I was able to preach and witness at the race track quite a bit. It was very fruitful. On Sunday mornings, leading up to race time, we would have a church service in the race tower or somewhere, and encourage everyone to come. Usually, it was someone who wanted to fellowship. Sometimes it was a fan who wanted to hobnob with "famous" people. Either way, it was fruitful. (Except for the guy who raced under the number 666. Several people tried to witness to him, but several of us are convinced that it wasn't just a show and that he was truly demonized.)
But, we can conclude from this that high speed racing is safer than walking, therefore walking is evil.
