He's done some very similar research. They're working on brain injuries and sleep as well.
Having formerly served, I'll tell you that you don't get a lot of sleep on exercises or other things. Your sleep patterns are disrupted. Having observed veterans not only of my generation, but older ones, my parents and people like that, I know these things tend to be lifelong if they're not treated. I applaud the research you're doing.
Is this something you could also develop for pre-treatment, before soldiers deploy, to try to identify people who may be susceptible to sleep disorders, brain disorders, PTSD, and start treating that ahead of time? You have the war fighter kit, which is something I suspect you'd use while you're deployed. It has earphones and calming music, or...?
