Can you share with us a little more about what you assume is common knowledge now about concussion? We do get some briefing notes before witnesses come. When you were saying, in passing, that you're trying to prevent this because you know they shouldn't have contact under the age of 14, I didn't know that. You heard Eric talk a bit about promotion and education.
I guess what I'm asking you is not necessarily whether we should be educating, but what you think are the big, undisputable findings now about the developing brain—the top three. I don't know if there are three; there might be a dozen. But it sounds like we can hit the ground running with education, with really solid evidence, and I'd like to hear a bit more of that.
