I don't know why the link didn't work--it works for me...
I can't put the text here because it's copyrighted (it's also a two-page article).
In brief, it seems head injuries are UP despite helmet usage also being WAY UP and cycling allegedly being DOWN 21% since 1990 or so (which I find hard to believe, and so do cycling advocates, according to the article).
Further study is underway to try to solve this apparent mystery.
One theory is that increased helmet usage has made wearers over-confident in some cases. Insurance analysts say this is a common phenomenon: perceived protection causes increased risk-taking.
That's about all there was to the article.
