Does the age of your ancestors at death tend to foretell your life expectancy?
I am sure there's a relationship but lots of things impact life expectancy, and in my case my ancestors life lengths varied a lot.
My mother died at 77 from lung cancer, she had smoked for about 10 years and quit more than 50 years before she got cancer.
Her mother died at 60 of pancreatic cancer. It does seem to be hereditary, two of her sisters and some of their kids died of it, but none of my grandmother's descendants have. So maybe I am safe.
Her father was a life long chain cigar smoker, a box a day, and he died at 99.
My father died at 85, but that was after my brother committed suicide, I think that's what killed him. He had been in good health before...
His mother died at 85 of a heart attack.
His father died at 95 of Parkinson's, he had been overweight most of his life.
His father's father died at 102 after falling out of a tree, whiskey was the problem. He's the one I want to follow!
So based on this I should already be dead, or could live another 32 years, maybe longer if I stay out of trees...
