Emphysema killed him. He smoked like a chimney. I'm sure there's no connection whatsoever.
Somethings going to kill you, I would feel lucky if I make it to 82.
So he had a few years shaved off his expected 95-year-life-span. He had a fabulous life and he probably enjoyed the heck out of the smokes. And think of all the time that existed before he was born, then think of all the time that will exist after his death. Whether he lived 60 years or 120 years really doesn't matter. Life is just a blip in the vastness of eternity. One may as well enjoy it.
We've all already been dead for an eternity when you consider that eternity is just as far in the rearview as it is in the future.
