I am sorry for your loss of your grandmother. I understand how difficult it is to have a loved one in a assisted living when they want to return home - heart breaking for you & your family.  My parents were older when I was born, so instead of losing a grandmother that way - I lost both of my parents.  My experience is - when someone is in their 80's or 90's they can go along ok - but that one fall or a bad cold - can accelerate their decline. Even if they "come-out" of the fall or illness - the rest of their lives is often one of difficulty.  As such, if RBG could recover from this fall - it would be unusual; however, she has/had access to medical care not available to us.
