Thank you, Chair.
Thank you to our witnesses.
General, I'd like to just briefly follow up. I recognize that you're going to be providing something in writing to us, based on Mr. Norlock's question earlier with regard to sleep treatment, etc., but I wonder if you could just give us a quick understanding of the difference between PTSD and depression, as it relates to causing suicide—what we know. And is there a connection between depression and a lack of sleep? Can you give us anything concrete on that at this point?
