My Great Grandma died a few months ago at 106. She lived alone in her own house and still drove up until a few years ago.
Even though she wasn't stuck in a nursing home or worse, it seemed kind of miserable and she would mention it herself quite a bit. Lots of seeing your own family die, along with every one of your friends. For perspective, she was born in indian territory before Oklahoma was a state, her husband died 78 years ago, and 3 of her great grandchildren died before her.
I've always wondered if I'd really like to live that long or not.
