I'm sorry your father is not doing well. I'm right at that age and have done all I can with legalaties to ensure my wife and children don't have to make MY decisions. There is a time in life where enough is enough.
For what it's worth: I think he's very fortunate to have a caring son to be with him.
The difficulties of employment in our country have created a lot of despair. Also a great deal of dissention and disgust. Something needs to be done about billionaires just taking more from working people. I had thought our government was going to try to make the inequalities better but it just seems to get worse.
Looks as if Health care is just going to go down the same road. Odd: Our nation revolted against the British Empire because of economic injustice and now our government is sanctioning the same injustices.
My Best Regards for you and your father. Hope it goes well. Sincerely.
