I'd like to make two points.
As you realize, I believe we have an oil problem in the world. It's because of something called depletion. When you start production, a well automatically depletes because the pressure depletes. Your production goes down. You're on a treadmill here, where you have to spend a lot of money just to keep production up. I would venture to say that the industry in the world spends 15% more a year and it gets nothing for it. There's no extra production. So we have a problem.
Exxon, I believe—and I wish I knew the exact number—spent something like $50 million a day and the reserves went down last year. It is not easy to find oil; it's not easy to find gas. Everything gets more expensive all the time. So that's the point I'd make.
