I was just overhearing Fox & Friends, and Glenn Beck just stated that the safer you make something, the more dangerous it becomes because people take more risks. Such as Rugby and Football. More head injuries in football and they wear helmets.

I figured I'd put this thread here because I fully agree. I ride my bike much harder when I'm in full gear, than when I very seldom hop on it without a jacket. I definitely won't be on the back tire at 45-70mph without one.
I couldn't imgine even going around the corner without a helmet. I'd ride bicycle speed.
