I would guess at something. I'll make a statement, and you can correct me. The World War II veterans are at a more advanced age. Many of them are in the last stages of their active living, in a way. The Korean vets' average age, I think we read, is 74. They are much more active seniors. I would think that we have a lot more to learn from the Korean vets, when we talk about post-traumatic stress disorder. They're still active in the community in many ways. They still have an ability to provide more information to Veterans Affairs in another study. I think you'd have a lot more to offer than some of your older colleagues who served in the Second World War.
