Some smashes have been timed at more than 250 mph, so you get less than a second to react. People who see a professional badminton match up close are always shocked at the speed.

I'm lucky in that I can't see myself doing an office job every day. I'm lucky that I can play my sport and go around the world without too much to worry about outside that. I think it's good to be happy with what you're doing.

In our sport, there's only two people, so if you're not winning, then you're losing.

I've got quite a good poker face. I'm known for being able to keep my emotions very much in check: no one knows how I'm feeling. I can be winning or losing but keep it very much the same.
