Damn that ***** dude. I lost my grandpa to Alzheimer's and a stroke about 5 years ago. It is really tough on the family. My grandpa was pretty much a genius, probably one of the smartest and hardest working person ever. I only remember his glory days of being a gruff old guy that loved me when I was little, growing up I had to deal with a shell of the person he was so, really nothing but bad memories. Plus my stubborn, neurotic grandma wasn't the best choice for being the caregiver. He was 84 or 85 I think.
I sure as hell hope that by the time I'm in my 70's they have a cure or treatment for that shit. I'd be more than happy going kinda young rather than be an incontinent or vegetable. Those are actually some of my only fears. But my grandma is 89 and still ticking but kinda frail. I just wish I get to be like some of those old men that are 90 and still working on cars, playing golf, hunting etc.
I really didn't start mourning until several months after the death. I was relieved at first because he and we didn't have to suffer with it anymore. If you haven't mourned yet and don't think you will, it will happen eventually.
Also, doesn't it seem weird that the day my grandpa died was when his hospice care ran out? Some family members still think that they euthanized him.
