I forget how lucky i am. I was without grand fathers by the time I was born, but I was around 40 when I lost my second grandmother at 95, and already an adult when my first grandmother died (not sure how old she was, but quite old).
I'm in my 60s and I still have two living aunts 88, 93, and my mum just died in September, 89 (smoked most of her life and didn't exercise). We live a long time on mum's side, and the non smokers on dad's side live pretty long too. I've an 80 year old cousin still in private practice as a physician (he's an eye surgeon).
