I can't even imagine a world in which parents would listen to me on this.
Me either! I wrote this list based on all the stuff I /wished/ we could have done for my folks. But Dad was proud and Mom is stubborn, as well as possessing a pathologic need to be perfect at all times, so any suggestion of help was rejected because she was perfect and there was nothing wrong to help. If Mom had gone first, my Dad would have allowed us to do some sorting/downsizing, perhaps signing him up for a meal service, but would have rejected anything that sounded to him that we were treating him like an invalid.
