I am not exactly amazed when people still deny they're risking their lives by riding without helmets. More like mildly interested in yet another example of the human capacity to believe whatever we want in the face of obvious facts, evidence, and (un)common sense to the contrary. Now, I'm quite willing, even anxious, for those who wish to risk their lives in such a manner to go ahead (pun intended) and do so. The way I see it, they stand to improve the human gene pool by possibly removing themselves from it earlier than necessary. They should win a Darwin Award, if they have not already.
However, watching the now-infamous headbutting incident at the TDF yesterday--and yes, Canvendish's legs won that sprint, not Renshaw's head--my first thought was, Yet another reason to wear a helmet. Then I thought about the possibilities. Would Renshaw have butted Dean if he, Renshaw, had been helmetless? What would have been the outcome if the headbutt were committed sans helmet? The answers might be Yes, he would, and Much, Much Worse--especially for all the non-butters behind them.
On the whole, however, my main reaction to the scene is disappointment. Not that a TDFer would stoop to unethical tactics, nor that he was evicted from the race for them--both are to be expected. However, I am sorry I revealed the history of my busted helmet (below) before now. Think how much I could have gotten for it on Ebay if I had advertised it as a genuine replica of the result of a Renshaw-encounter.
