She recently turned 94 and has been living on her own the entire time. She buys her own groceries and takes care of everything around the house. Prior to my aunt's passing, she had moved in with my grandmother. Her eyesight has gone to some extent and her hearing is difficult at the best of times, but she's kept on trucking.
And speaking of trucking, she's had a rather peculiar quirk in that she likes to move. She has a friend who helps her move every so often. My mother has quite seriously never written her phone number and address in anything permanent. My dad, frankly, has always been a little ashamed of his mother.
It's caused a little friction from time to time. My mother and father expended a nonzero amount of effort to find a place near us for her to live and managed to get her to move in twice. When she moved in, everything was great. Her neighbors were great, we'd take her to lunch on weekends, and so on. When she moved out, she complained that her neighbors were horrible people and that she didn't like the place she was living and so on. Virtually everyone was a little annoyed that she had chosen to move away from us. It never really bothered me -- more or less on the theory that she's lived long enough to know what she's doing.
After that, my mom decided that when she passes away, we'll have her ashes rotate every 6 months or so between a half dozen cemetaries.
It is in any event appropriate that she had this heart attack while she was moving.
