I don't know because they would have to be informed not only by the kind of observations we have and we find when we look at this relationship between sleep and mental health. With military service members from the get-go, I believe, there's a self-selection bias. To be able to even complete the training, you have to be able to take quite a bit. I've always said that the people I've worked with have constantly reminded me of how resilient and how tough they are, and I do believe that it's a self-selected population that is just at a higher capacity to take on and sustain chronic challenges, relative to the general population.
Regarding the kind of policies we would make, we would have to be careful that the signal we convey with these policies does not therapeutize or make the military people seem or sound vulnerable because of the kind of work they do. Those are people who choose to do what they do, and I think there's a selection bias in who chooses to do that. We'd have to be able to evaluate, which we haven't done much, what the factors are that provide resilience and strength to allow these people to take it much more than I can, for sure.
