Helmet debat

I live in Texas where everything is bigger, and I guess that includes the vanity. So I began recently to wonder what is it about the western sports that insist that participants wear cowboy hats. I understand that people look "dorky" in helmets, and you can look at the post below and see how I look, but I think I would rather look dorky while I ride than have an accident and not be able to walk or possibly worse. So, My question again. English sports and racing require helmets, even for adults, but western events, with the speed and unpredictability of all the animals involved do not. It doesn't make sense to me. See the following youtube video to maybe get your brain working more on this. http://www.youtube.com/watch?v=M0-A6T45xB0&feature=related

For more information about my opinion read more of my posts, especially the one labeled helmet.
