For us it is 62 years, and he is been showing dementia issues more and more, as he is going through change i have learned to back away from plans or ideas, but had to go through changes, even in my denial and his. I have let people know not to plan visits as the stress becomes an issue. But still want to encourage him to do things for himself and not just take over everything. Never know what mood or reaction will follow, one day at a time, one hour at a time. Right, sometimes pushed, sometimes pulled. Thank you.
