I think that the reason why people start smoking is family members' example. Everyone wants to be healthy and prolong life. That is why you must understand why smoking is a harmful habit and why you should never take up smoking. Smoking causes a lot of diseases such as cancer, bronchitis and etc. It is hard to give up smoking. When you become addicted to smoking, you will feel lonely, depressed and anxious. The second reason why I DO NOT ADVISE YOU to start smoking is because smoking IS NOT FASHIONABLE anymore!!!
