Yes, there has. Specifically, I would talk about our concern about the health and safety of players. From a head injury perspective, I think there are two components. It's frequently the issues of concussion and repetitive head trauma. I think everyone's worried about both. I don't know which one we worry about more, but from a repetitive head trauma perspective, the Football Association in the U.K. is now 18 months into something they call the FIELD study. It's headed by Dr. Stewart.
We have been in touch with the FA. We're going to follow that study with interest. It will talk about the long-term follow-up on the health benefits and harms of playing soccer.
