It's a difficult question to answer in regard to just making a list of the top three that we're good at. I look at the trade figures. We are very present in the extractives. We're very good at mining. I was just in South Africa at the Mining Indaba conference. We are good at that and we do that responsibly, so we also have corporate social responsibility.
By no means is mining better than information and communications technologies or aerospace. Aerospace is a very big export-driven industry as well. I'm looking at it from an export perspective.
