Death by longevity is a curse on one branch of my family tree. When I was little the oldest person I knew was my great grandmother, my mother's mother's mother. I don't know how old she was when she died, but she was well into her 90s or older. Despite being cursed with longevity she was blessed with senility, we had a lot of fun playing together. Then my brother was born and she passed on shortly afterwards.Her daughter, my grandmother, lived to 100. Two of her children, my great uncle and my great aunt, lived to be 101. Aside: great uncle's wife passed away the year following his passing at 99, they had celebrated their silver anniversary a little bit before he passed, that was pretty cool.
Another daughter, my great aunt, was the oldest person I've ever known. She was 105 years and 10 months old when she passed away. On my birthday. That sucked.
