My father is in his mid-70s and has some health problems. His biggest issues are not wearing his hearing aids all the time and memory problems, so the general old people stuff. He's not senile or anything but it's enough where I'm worried about the future and want to try and slow it. Any advice? I can't expect to change him since he's stubborn and he's blown off stuff like this in the past so it's just something I'm trying to get ideas for.
