I wear a helmet because my loved ones asked me to.

Its as easy as that. In any cause, the huge jumps of logic that the original study states are hardly convincing. Maybe sprinters should wear helmets... if they wove in and out of rush hour traffic in the middle of the road. I will continue wearing a helmet on the off-chance that I get into an accident at ~14mph, and you can not wear a helmet if you want. Why the ceaseless discussion on the topic?
