The biggest problem is most of this is pure BS,created by shrinks to justify their existence,and slackers looking for an excuse to get disability retirement.
Back when I first started going to a VA hospital to get treated for what became known as "Agent Orange",there would be large groups of veterans gathered around the mess hall at lunch time sharing and asking others about why they were there.
All I had to do was mention "Agent Orange",and I would have a crowd gathered around me,asking me "What did yours look like and what were the effects? Mine went away,and I forgot what they looked like so I can't tell the doc in order to get help and disability payments."
So I just quit telling anybody why I was there,or making up lies and saying stuff like "getting a dental appointment".
One example is a guy I saw there EVERY time I went. BIG healthy-looking black guy in a wheel chair. I figured he got wounded or injured some way and needed the chair,but was never rude enough to ask him about it until one day I mentioned that I would be driving off the VA property and to a Wendy's to eat lunch. He asked me if he could ride there with me,and I told him there wasn't room in my car for him and his wheel chair.
So he just stood up and walked around me to prove he didn't need the chair. I told him to go bleep himself.
Don't get me wrong. There ARE patients at VA hospitals with VERY serious problems,but it SEEMED to ME that most were there trying to scam the government out of a disability pension.
If anyone is interested,I can post a VERY funny (to me,anyhow) story about a USMC VN Vet (wearing USM Utilities and boots) who I saw walk into the VA hospital in Denver to ask for a drug refill,and what happened.
