I certainly think we can provide some information to understand the data and how it is collected. There are challenges in the data. The economy has evolved over the years. As I think we talked about earlier, what we counted 10 years ago and what we're counting today may be slightly different. So we'll try to explain some of that.
With regard to your idea of going from one shift to another shift and how that impacts on the service economy, I think we should be able to pull together a bit of information. To what extent you can extrapolate that would be questionable. But most assuredly, if you start taking a look at the oil and gas industry, there is lots of high-end engineering informatics technology. There are lots of services. It is not as most people would think at first blush; there is a whole host of things.
We could perhaps provide a primer of sorts, if that would be helpful.
