My father's mother, Grandma Annie, lived to be over 100, which was a surprise, as she was sickly for decades and a former heavy smoker. Her son, my dad, only made it to 65.....
The oldest person in my family (so far!) died a year ago this month and she was 101. I say "so far" because I have an uncle now who is 98 and doing very well.
In my immediate family, it's me. I'm not sure how old my grandfather was when he died, but it might be close to where I am. My mother's side was hit hard by cancer, most died very early.
I have a brother who is 81 right now, he is at an older age than my parents or grand parents ever reached. My family has always lived hard and died young.
