Nonetheless, that all being said - I suspect that if you actually WERE walking on a roadway heavily traveled by cars and trucks, a case could be made that walking there, without a helmet, is sub-optimal
And of course, since slips, trips, and falls in the home are a likely cause of brain injury, you do wear some kind of protective headgear in your home, right? And you do sit while washing your hair to minimize the risk of falling while showering and not wearing a protective hat.
Actually, I have no issue with wearing a helmet, its just the attitude that if one values their brain they will wear a helmet without considering other more likely scenarios for brain injury go unprotected. That I don't understand.
