He's in hospice care, my mom said he might live 1 week, to as much as 1 month. I'm very sad to lose the old man, he's been a part of my life for, well, my whole life.
When he found out I had a huge interest in WWII, the nicest thing a relative has ever done for me, he gave me his old WWII-vintage Army-Captain bars. He finished the war as a Captain.
I got them in a display case along with my Uncle's Purple Heart and Bronze Star my Uncle got in the Battle of the Bulge.
My grandpa mainly fought in Africa and Italy during the War. In Italy in particular, he had a much higher opinion of the German's general, Albert Kesselring, than he did his own, Mark Clark.
My favorite story about Grandpa, one day we were sitting down to play a game of scrabble, and he spells out "A-N-Z-I-O" Anzio, with a triple word score with a Z. I tell him he can't use that since it's a proper noun. He then starts telling his old war stories about fighting in the Battle of Anzio, and god damn, it was such a great story, we wound up allowing it, and he WON the game.
There's a life after death, so dont worry..
Good luck!
