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.
