Thank you very much.
Doctor, it's been an excellent presentation here today, and some great questions right around the table.
I know for everybody around the table, when we went to school, there was what we know now as ADD or ADHD, but they used to just be the bad little buggers who couldn't sit still for most of the class. So as we learn more about PTSD and become better at recognizing the actual cases, since statistics have been taken, and over the various conflicts that not only our own soldiers but our allied soldiers as well have been in, are the numbers increasing as warfare changes?
There has been an obvious change from our Second World War veterans to what our soldiers deal with today. Are the numbers of instances increasing or decreasing? Can you make a comment on that and rationalize the numbers, why they are going that route?
