Thank you.
I'm a bit confused, because I believe you just said that most countries, or all countries, believe in the debriefing, the decompression, whatever you want to call it. But you're saying the studies we have now don't prove that that's going to avert PTSD. So what do we do at this point? If we're not sure it's working, yet everybody's doing it—help me here—where do we go from here? Do we need a more in-depth study? I would have thought if everybody in the world was doing it, there would be some value to it. Are you saying the studies that have happened up to this point don't bear that out, don't show that?
