Livre d'Or

Well, I bang mine from time to time - I had quite a good prang 3 weeks ago, concussion, leaking claret from the forehead. But... no permanent consequences, I and I reckon the odds are good that if I were a foam hat wearer I'd have smashed said foam hat and now be proclaiming how it "saved my life".

The most egregious case of this I know is Simon Brooke, who crashed into granite boulders on a twisty descent at 46mph, breaking his neck (thankfully making a full recovery) but suffering no head injury at all. He would be proclaiming his helmet saved his life... except he was wearing a cotton cycling cap.
