I'm really surprised to hear you smoke, as smoking is supposed to contribute to premature aging. adding an extra 14 years by the time a person is 70. But smokers have never bothered me, probably because my father chain smoked all his life so I grew up with it.

My sister was a heavy smoker until she had a dream in which she felt God was telling her to quit smoke "or else." This was about 25 years ago, and she quit cold turkey after that dream, never smoking another one.
