That's happening in Netherlands right now. It is starting to happen here in Canada, but we are behind in taking measures pre-deployment. There are a lot of concerns about that, because, if you see indicators of vulnerability to PTSD, does that mean that we do not deploy someone? The debate is, do you want people who are hypervigilant, ready to go, are able to grab somebody from a disastrous situation and carry them to safety, and things like that, or do we weed them out with early predictors?
It's a very interesting question of whether we can predict who's going to develop PTSD and who's not. The concern of the user community is that it will be used in a negative way, or with how it will be used. Those are the kind of debates that are ongoing right now. But I think we need to get to that point where we assess people before they go, during, and afterwards to have a much clearer idea of what is happening to the physiology and chemistry of the brain.
