When I was young, I didn't know much about the harmful effects⑱ of smoking. I didn't know, for example, that it could do terrible damage to⑲ your heart and lungs⑳ or that\s\up1(21(21) it was more difficult for smoking couples to become pregnant\s\up1(22(22). I certainly didn't know their babies may have a smaller birth weight or even be abnormal\s\up1(23(23) in some way. Neither did I know that my cigarette smoke could affect the health of non­smokers\s\up1(24(24). However, what I did know was that\s\up1(25(25) my girlfriend thought I smelt\s\up1(26(26) terrible. She said my breath and clothes smelt, and that the ends of my fingers were turning yellow\s\up1(27(27). She told me that she wouldn't go out with me again unless\s\up1(28(28) I stopped! I also noticed that I became breathless\s\up1(29(29) quickly, and that I wasn't enjoying sport as much. When I was taken off\s\up1(30(30) the school football team because I was unfit\s\up1(31(31)， I knew it was time to quit smoking.

　　I am sending you some advice I found on the Internet. It might help you to stop and strengthen\s\up1(32(32) your resolve\s\up1(33(33). I do hope so because I want you to live as long and healthy a life as I have\s\up1(34(34).
