I think you have to bear in mind the comments of Mr. Upshall about research and pharmaceuticals. We had some data presented to the CMA by an expert in genomics that suggested that the biological companies had three main areas of interest in their research programs that they were expending a vast amount of money on. One was hypertension, the treatment of high blood pressure. The other two were male pattern baldness and obesity. You can make of that what you want, but I think it's difficult to know sometimes what the results of pharmaceutical company research really are in terms of the amount of value they get for the money that they expend, because a lot of that data is proprietary and never sees the light of day.
I'm not sure that I can answer your question. I'm not sure anybody but the pharmaceutical company could answer that.
