Thanks for the article. Wearing a helmet is just good common sense. Those of us who have ever scratched or cracked one know their value. Especially with the improved comfort and reduced weight it is difficult to find a valid reason to not wear one.
I think intelligent people will wear bicycle and motorcycle helmets, as well as seat belts in the absence of laws. If we force those adults who would not ordinarily take these precautions to do so, we may be affect natural selection and end up with a society like the one in the movie Idiocracy.
