Smoking
Hey Mud -
Neither my wife or I smoke or ever have, but I can understand your concerns. I've seen a lot of couples where the husband has quit smoking and the wife hasn't, so it's a fairly common situation.
Do you have kids or grandkids? I think the greatest motivation comes from a young child pleading for an adult to quit so they can be around a lot longer in the childs life.
My father, a grandfather, and my mother-in-law died from diseases directly linked to their smoking and none of their deaths were pretty. My father died at the age of 44 when I was only 7. That alone was enough for me to never smoke.
As others have said in this thread, none of us get out of here alive - but there's certainly no sense in hastening the inevitable, especially at the pain and sorrow of others.
Good luck in your efforts.
