I think that's a question for you to ask the doctors and the sports administrators. I think what they will say, in part, is, “Oh my God, the number of players, the doctors, the ability to get appointments....” Whatever those answers are, at least in part they do represent answers and represent significant obstacles.
I think those are questions that you ask to find out the extent to which that represents a big part of the answer, a lesser part of the answer or even less than a part of an answer. I think that's part of the discovery that you're going through and that you have the chance to do, because you're going to be able to ask those questions of people who are attempting to apply this on the ground.
