Many things are dangerous to our health. Life, after all, is terminal. To a non-smoker perhaps. To a smoker, and there are many, it is a pleasant habit for the most part. While we smoke we observe many unpleasant habits exhibited by non-smokers.
Many people eat too much, drink too much, talk too much.
Persons who are excessive in other areas are just as unpleasant as they think smokers are. Resolve NOW to forget what others think or say. Their opinions are no better than your own. Start to think about what YOU want. It's time to be honest with yourself.
