 That's a really difficult question to answer because it's one thing that there's a huge promise of newer jobs and newer energy industries. But the reality is that the oil and gas industry, at least in the United States, still has a number of job openings. And for the most part, especially college graduates that go to these industries, make some of the highest average salaries in the country. Those who graduate from chemical engineering or petroleum engineering. And this is a question that's not theoretical. We deal with it.
