The Importance of Exercise in Concussions

World Rugby's chief medical officer talks to HL about the practical side of concussion research. World rugby is obviously your focus, but what has rugby done around this issue? In other words, what have you taken away from a conference like this and how do you implement it? We're emboldened by that because that's the same thing we're trying to do. It's more difficult in rugby than in American football because, you know, American football's so discreet. But we see the success they've had. There's a lot going on there.
