Thank you for the question.
Some of the same points were raised by Mr. Doidge, but some are a little different, because for us it's a change in demographics.
For a long time, Veterans Affairs had an older cohort of veterans, but since the war in Afghanistan and some of the peacekeeping missions before that, the average age of our veterans has gone down and the needs of the veterans have changed.
The newer, younger veterans have different injuries we have to treat, and some of the medications used to treat some of these new injuries are a lot more expensive than some of the traditional medication we may have used in the past.
A lot of our changes.... Although the demographics are going down—we had over 700,000 veterans and now we're around 670,000—the needs are more complex, the medications they are using are different, and the costs of those medications are going up. Like I said, some of the injuries and illnesses we are seeing are a lot more complex than they were with some of our previous veterans.
