My maternal grandmother was in her 90s the last time I saw her. She had one piece of advice for me: "Don't grow to be really old - it sucks!"
My great grandfather was 96 and in the field putting up hay when he decided to go to the house, sit on the porch and call it quits. Some have it better than others. I still love the part in Grumpy Old Men when Ossie Davis had passed away. I can't remember who asked who (Matthau or Lemmon), but it went "How'd he die?"
He went in his sleep.
Lucky bastard!"
