If I may add, I could reverse the question and ask you, or anybody who's asking these sorts of questions, what is GM? What does that mean? That's what I was trying to get across in my presentation.
There's a certain understanding of what GM means today and from the last few years, and that's going to shift very quickly over time. If we're going to put a labelling regime in place, it ought to be nimble to keep up with it all, and I don't think that's possible.
