The Down Side of Helmets

Troy Aikman is against the use of the helmet in football.
“For years, I've said the best way to eliminate head injuries is to take away helmets. Players would be a lot less willing to jump in and stick their heads in if their noggins weren't protected. I used to say that tongue-in-cheek. But I'm starting to believe that's a pretty good idea.”
Seems the facts back him up, too, as witness the much lower concussion rates in rugby, where they don't use helmets.There's even a  public health term for this phenomenon: "risk disinhibition," wherein  
people respond to technical advances by exposing themselves to greater risk than they ordinarily would.
Which is another reason  the popes are right about AIDS & condoms.
