If I can come back to the issue of pain, pain is just a relative term. If you can guarantee that the rules will be the same for everybody in the world, then there's no such thing as pain; then it's a challenge. The minute you have rules that are set differently against competitors that are formidable on a worldwide scene, then it becomes a big issue and becomes pain. So we have to remind ourselves that pain is only defined in a sense of relative competitiveness among the players on the world scene.
