Okay. Then to my last question, because I have that feeling from the chairman that this is going to be chopped.
You said that right at the moment you don't have the capability of knowing which personalities would be predisposed to post-traumatic stress disorder. But is there research going on right now to see, as we get these cases, which people are more likely to be affected and, of course, less likely? Of course, you can tell the outcome would be to stream them into the positions where they would best fit.
