For those of us who do not ride motorcycles, helmets seem like a no-brainer (no pun intended). Riding a motorcycle is highly dangerous, after all, and helmets have been proven to save lives. However, long-time motorcyclists disagree, and claim that it is young, aggressive, inexperienced bikers who are causing motorcycle accidents and suffering injuries and fatalities as a result. "Why should the risky few ruin it for the rest of us?" these experienced riders ask. Yet, medical professionals and advocates say that the high financial cost of traumatic brain injuries and other common motorcycle injuries renders the lack of mandatory helmet laws a public health issue.
