I wanted to touch briefly on the peak oil theory too. Mr. Diwan talked about how much oil is out there, because we really don't know. There's a gentleman, whose name is Nansen Saleri, who is a former Aramco executive, I guess, working with the Saudi oil company. He was saying that the globe has consumed only 1 trillion out of a grand total of 12 trillion to 16 trillion barrels of oil. He, along with Exxon Mobil and the U.S. energy department, all argue that the high prices are propelling companies to innovate and invest more, and as a result, supply will rebound and prices will fall from current levels.
Do you believe this is true? Mr. Diwan, do you want to start?
