Hmm. I do not know. Truthfully, I'd never given it much thought.
I will note, though, that my Father-In-Law was a Vietnam veteran. He was proud that he served, but he never wanted to talk about it. He'd get real vague if you started asking, and would change the subject if you kept on. I do know that it was a hard time for him, and I think that he suffered some Agent Orange related issues, for the rest of his life.
My Grandfather served in WWII. He recieved a few medals. He was a lifelong student of history, so he WOULD talk about his war experiences... But, he hated to do it. It was a very terrifying, very miserable time for him. He'd have preffered to forget about it.
And, perhaps that has something to do with it. Maybe the living heroes just don't care to dwell on it, because it was such a terrifying and miserable experience. I also have noticed that most Heroes don't consider themselves as such; just an ordinary human, placed in an extraordinary circumstance, doing the right thing. I don't know; that's all I got, off the top of my tired head
