Well, we're not talking about those sports, but we do know that head hits in such things as hockey and football are very serious, and people have long-term effects from them. In fact, I understand there's a lawsuit going on in the U.S. from NFL players against the NFL for the effects of concussions during their careers.
We do know that those things happen, so it's our position that we should advocate to prevent those things from happening rather than waiting 10 years out to find out the long-term effects of many hits to the head, and then say, look, we should have done something about it.
That is our position.
