One of my grandpas was an alcoholic, did not much more than sit around, drink beer, and go out to eat pizza and roasted chicken about once a week for the last couple of decades of his life. He lived until 100.

The other had one of his lungs shot by tuberculosis, but despite that, smoked his entire life. Not particularly active either after retirement. He lived until his late 80s (EDIT: just checked, 85 actually).

EDIT: Obviously staying active is important for good health but anecdotes are not super informative.
