Here's a thought

Helmets might be the reason that there are so many head injuries in football. Counter-intuitive, to be sure, but think about it; if you didn't have an inch of foam around your head, would you bang it against another player?

I always thought that real men played rugby or Aussie rules anyways. You can't put on an extra 100 lbs of muscle and fat if you actually have to run around with it.
