Can't wait for the follow up, "How I'm dealing with my Traumatic Brain Injury"<p>Seriously, I get that one can rationalize away : <i>"I have never been in a bike accident nor experienced a close call, though I know what has happened to less fortunate bikers. I try to be cautious: I don’t fly through intersections, and I always look both ways. I believe the helmet has limitations and won’t protect me in many kinds of accidents. "</i><p>Helmets do one thing really really well, they mitigate brain trauma. Sure they look stupid, sure they are bulky, sure they take time to put on and put off. When you lose control of your bike, or it is taken from you by circumstances beyond your control, a helmet will give you a fighting chance to avoid having your greatest asset made irrelevant.
