smoking is one of the best habits nowadays. some people start it at a very young age - as a way way of showing off or trying to make an impression on somebody. Or maybe just to demonstrate how mature and independent they are, i don't know exactly why. i suppose everyone has his or her own way of aquiring this bad habit. At first they don't realise that it can last till the end of their lives with a lot of difficulties trying to get rid of it. They believe they can give up at any moment, how naive they are! the idea that it's time to give up comes up to their minds only when they become aware that they have got some health problems. At this point they begin to understand that giving up smoking is not so easy as they used to think it is. They turn to different methods, however they help not so often as you could suppose. To my mind, only your strong will and desire can help. Of course, the person willing to give it up shoould switch on some activities that would help him or her to forget about it: try backpacking, trekking, cycling or what-not. And the support of their nearest and dearest is the main factor? in my opinion.
