My dad died at 89, last September. Up until the last 4 months, he was driving, visiting friends, socializing. His physical status was compromised a bit, but he was never active in sports. His mind was sharp, and he read voraciously. He worked until he was 85 or so. Three out of four of my grandparents lived until 91-92. They all had really good qualities of life. My grandmothers might have had an even better quality of life if they had been active, but one lived independently in her own condo in Florida and died peacefully playing bingo (I know, this was a source of amusement to all of us). She had a boyfriend, who was 15 years younger. My mom's parents lived with my aunt for the last 10 years or so, but the only reason my grandmother was a bit frail was because she didn't move. When my mom would come to visit here, she got my grandmother up and walking. Then, my mom died at a young age, and my aunt was too much of a b**ch to do anything. She hired a home health aide, instead. My grandfather worked up until he had a car accident at age 90 or 91, and he died as a result of all of the anti-inflammatories they were giving him; he had an ulcer. He may have lived even longer, if it weren't for that. My grandfather made more money in the last 20 years of his life, than at any there time. He played football and ran track at BU in the 1920s and always was active. They all were cognitively with it, read, kept up with news until the end. Both of my grandmothers were gorgeous until the day they died.
