When you get a typical injury, you're given a time frame; you're gradually working towards getting back. With concussions, there is not generally a time frame or a span where you're feeling better. You feel like you're getting better, and it can be one day and you're back to where you started.

I think every athlete will tell you no matter what sport you're in, when you train so hard and when you care so much about doing what you do, there's a little bit of nerves that come with that. But nerves that won't prevent you form performing, nerves that, hopefully, allow you to be that much more motivated and inspired to do well.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

Some anthems are great for sports. You've got the Russian national anthem... 'O Canada,' how wonderful is that for hockey... but I chose the Italian national song because at my first World Cup, I saw the Italians play four times, and they won all four times - they won the championship.
