I know about giving "permission" to die, but although his health is deteriorating he has no terminal diagnosis (other than being 97). I don't know how or when to broach the subject. I don't want him to think I wish he would die, but I want him to know if he's ready it's ok. Also with him being deaf I have to write everything to him and comprehension isn't always there, especially with anything lengthy. Just writing "It's OK to die now." seems a little harsh to say the least. Any suggestions??
