I finally found out what is wrong with my grandpa. This is what's wrong: 2 leaking heartvalves, 3 coronary arteries that are in very bad shape, arteries that are in very bad shape and a heart that's in very bad shape. The surgeon said, and I quote:

"IF we operate you, we have to replace the valves first. If you survive that operation, you have to stay in the Intesive Care Unit a very long time. And then, if we operate on you again, you have a big chance you won't pull through."

So gramps said "I think it's best if I go back where I came from then" and the surgeon agreed, with pain in his heart.

And replacing his heart isn't an option either because 1. gramps' arteries are in very bad condition and 2. he's too old (83).

Only thing that can be done from now on is enjoying the time he's still with us. He has 16 pills to take per day to keep his bloodpressure as low as humanly possible. Big side-effect is that he gets very cold. But at least he's still alive.

Oh, and you'll NEVER get him even CLOSE to a retirement home. Gramps is very clear in that "I'll die in my own home."
