The Biggest Database of Concussion Diagnosed Nurses in Rugby

Rugby has the largest database of concussion-diagnosed nurses in any sport. NFL have 16 matches a weekend, 15 excluding buyers sometimes,. We have 40 matches a weekend. And it's played over the entire year because it's Southern and Northern Hemisphere. The databases enormous compared to anything they've got. So that's where we have done a lot, I think, more than any other sports - borrow from what we've done.
