and that hurts you how?
BTW I wear a helmet 99% of the time & live in a no helmet law state.
That is very wise and sensible .
Wearing a helmet is essential on a bike, I just read a comment about how sports bike riders hit the ground harder LOL, most accidents happen in built up areas at slower speeds so that comment is not right, if your head hits the ground at almost any speed you will suffer badly

I also dont see how full face helmets are more dangerous, they protect your chin area whereas open face gives no protection in that area .
