With your permission, Mr. Bachand, I'm going to answer in English because that's a little easier for me.
You have to be very careful about what you know for certain and what the research seems to indicate that is not yet definitive. You have to be quite careful to separate those things in your head.
We believe that having had a diagnosis of post-traumatic stress disorder in the past does make you at somewhat higher risk of having a reoccurrence of this disorder if you're subjected to combat stress in the future. It's not 100%; it's not a guarantee.
What we don't know is exactly how big that difference is.
We also know that other kinds of things in your mental health background have a similar effect. I think Dr. Brunet alluded to a history of childhood abuse of any kind being a serious risk factor, which we actually don't screen for--for a whole lot of reasons.
So we know there are risk factors. It really is a matter of serious professional judgment--and they do take their responsibilities very seriously--to assess whether somebody who has been treated and has done well, has returned to duty and is performing well in their job, is well enough to go back into theatre. That's a serious decision. It is not taken lightly.
But if you come out with a blanket policy that says as soon as you have had a mental health diagnosis and have required treatment for a period of time, you can never go back into theatre, well, that's a recipe for perpetuating stigma and for driving the problem underground if I've ever heard one. So we don't do that.
It's case by case. We rely on the best judgment of our mental health professionals on whether people are or are not ready to go back.
