It's been said recently but it's odd. Odd that I know personally a couple of cyclists that have fallen and claim to have been saved from worse injury by a helmet or that claim to have had their life saved by one, more than that all the cyclists I know claim to know yet another circle of cyclists that have also been saved in some way by wearing a helmet, even some of the non cyclists I know claim to know someone or know someone that knows someone that's had their life saved by wearing a helmet, that's an awful lot of people. But there is not one story, not first, second, third or any other hand story that has been shared with me that involves any unhelmetted rider hitting their head and suffering any sort of injury at all, nada, zilch and so on and so forth.
Now of course that doesn't mean it doesn't happen, but there's something odd going on. Better bike handling? Less risk taking? Maybe a little bit of exaggerating? Judging by the posts of certain person on these boards that seems to claim they've smashed yet another helmet every month or so I suspect there's some efforts to justify the choices being made. I dunno, like I say, odd.
