Give up smoking

'Smoking is harmful to you health',If you are a smoker,you must know what I say.pick up a pack of cigarette you'll find it.But I'm interested in smoking.When I was a child,I saw my dad smoking,it looked like  very adult.So when I was still at college,I have became a smoker.
From then to now,I have smoked for ten years.My friends advise me to give up smoking.But they do not realize an important thing,I am not interested in smoking,I'm only interested in enjoying the free time when I was smoking.
Are you a smoker?
