Okay.
I would like you to go back to telling us a bit about what is common and not disputed anymore.
Rosemarie was talking about her daughter and how much her daughter loves sports. That has been the problem perpetually. Kids love it, and then parents feel good when they see their kids doing it. The kids get positive reinforcement, so they do it. First thing you know, you're a fan paying the money for a professional sport; it's not just about the amateur. It just cycles and cycles and cycles.
I would love to bring it back to what we know now that we didn't know in the 1990s. What is not disputable?
You were on a roll a bit, and I would love to hear more about that. Even if you just want to talk about the developing brain and contact sports, for instance, when did we find that out?
