I served stateside, 1964-66. No duty injuries. When I retired and moved to McAllen, an old neighbor, WWII vet, told me I should sign up for VA, that in Texas they treat vets real well. It just sounded wrong to me that I would get medical care with no service related issues, and no combat. But, he insisted that I could. I am still not sure about it.
Well, I don't normally go to the doctor. Here in Mexico my best friend is a doctor, and I loaned him money to build his clinic and he has never paid me back. So, I do get free meds. But, usually I tell him what I need, and it isn't much. I think I have only asked him for help once, a few years ago, when I forgot what ant bites look like. He didn't know either, but gave me some stuff for the pain.
No prescriptions, except Androgel which doesn't need one. With Atkins, my b.p. runs 113 or lower. Feel great at 71. And, I do have the Medicare, but so far have never used it.
