Oh, very much so. This is the Baltimore study. We've looked at that. It's very important. That's an experiment in itself. We have a number of soldiers who have depleted uranium in their bodies through an unfortunate friendly fire situation. They have been identified. They're followed at the veterans hospital in Baltimore. They are followed regularly. They have been followed for 20 years.
What distinguishes them from others is that many of them still have depleted uranium in their bodies, and they keep excreting it, so it's like a continuous exposure. From that, you can draw certain scientific conclusions.
There are not that many of them. There are fewer than 100, but it's still the best there is, you know.
