You may say that again, and many people do; that doesn't necessarily mean that helmets "work" as well as you think or say, at significantly reducing the severity of head injuries that are the outcome of a bicycling accident. Further discussion of "helmet working" (the actual reduction of the severity of injury suffered by bicyclists in accidents) should probably be posted in the helmet sticky thread.
