My grandmother who smoked lived to be 94 and was pretty feisty and happy/healthy until just about the end.
On the other hand, my dad has COPD, terrible circulatory issues and had two strokes...one in his 40s and one in his 50's. The last ten years have been hospitalization after hospitalization and now he's been in the nursing home for about 2 years. He started hospice care about 6 months ago. He's come down with pneumonia this week and obviously will not be hospitalized this time. It's a pretty sad situation
He smoked heavily and never stopped once, drank heavily, never exercised, just took horrible care of himself.
No more smoking for me.
