Christians: what do you do to your parents when they get old and need much care??!!?

Well, my mother is in a home, for HER safety , Alzheimer's..... My dad is almost 82 and in better health than most 1/2 his age.... My mother N law died years ago.... My father N law is fine and has a YOUNG wife to take care of him.... NOT that it is any of your business.... But most people, no matter what *faith* or lack there of, do what they can as best they can..... go in peace... God bless
