I understand the philosophy and rationale of not wearing a helmet. I also understand the rationale of wearing a helmet, especially since I have hit my head in the two accidents I have had and each time I am convinced that the helmet saved me from a serious concussion and or major subdural hematoma / brain injury.

I think the most graphic example I can offer is the biking safety instructor who likened your brain to a raw egg and then had each of us drop an egg from eye level to the sidewalk.

It is a matter of choice and I try not to judge one way or the other.
