Just a story about helmets. About a week ago a motorcyclist also carrying his 10 year old son, was driving down a busy street when a driver in front of him flicked a cigarette out the window. This angered the motorcyclist who went into the left hand turn lane to keep pace with and yell at the occupants of the car. Although it is not clear what happened, a collision occurred and the motorcyclist was severely injured. He later died. His son, who was wearing his dad's helmet, broke a bone or two but was otherwise ok.
So what's the moral of this story?
First, don't flick your cigarettes out the window.
Second, if you are flicked at, don't get angry about it.
Third, if you are carrying your 10 year old on the back of your bike, don't act like an a##h###.
Fourth, if you do act like an a##h###, make sure you wear a helmet.
Any one of these actions would have prevented this kid's dad from dying. Helmets may be a choice for adults but the injuries that result from not using them affect more than just the rider. It's a lot easier to regulate helmet use than innate stupidity.
On the other hand, I guess the argument could be made that not requiring helmets is a good way to clean up the gene pool. I don't think that 10 year old would think so though.
