Dad was 96 when he passed two years ago. He actually out lasted his first pace maker. He was on diuretics for so long, that it finally took it's toll on his kidneys and of course his heart.
Both his kidneys and heart got so weak he just couldn't go on. Both organs started shutting down simultaneously.
There is something to be said for the quaility of life.
You have a very hard road ahead of you.
My Prayers.
