those are the anecdotal accounts I speak of..I've got two helmets myself
with trophy cracks hanging in my basement...
I firmly believe I would have been in the trauma ward for one of those
falls if it weren't for the helmet..

just think, by enlarge people thought smoking wasn't unhealthy 50 years
ago...sadly, change happens one funeral at a time.

Well, I have five broken helmets that seem to demonstrate a viable
link. Two of them were broken into separate pieces when I went over the
top of my bars and one had and entire side shaved down from sliding
along the road. The other two were more "minor" in the they only had a
crack up the side so I might have survived in some way with some general
motor function.

These arguments against brakes and helmets seem very silly, as if
taking laws that attempt to mitigate the risks in certian activities
violates our liberty. Sorry, but stupidity is not a fundamental right.
The costs and benefits are balanced, and in this case the cost of
requiring helmets and brakes seems minor compared to the potential
injuries. The fact is that society passes laws all the time with
respect to products and activities to protect us and it always adds some
cost. Some we like and some we do not.
