I'll give a brief response. I think this has to be located on how much we want to up our game, if I can use those words. What I observe around the world is that those who want to up their game significantly because they're way behind—and we see that in countries like China, for example—have targets like doubling their budget in the next five years and so on.
There are others who feel they're in a very good position that they want to maintain. They may have targets of doubling in seven years. This is the way I think we need to look at that. It needs an assessment of where we are and where we want to be.
