Stop Smoking To Increase Your Life Expectancy
If you smoke then that is the number one factor you can cut out to increase your life expectancy dramatically. Also once you stop smoking the lungs repair themselves and the more smoke free years you have the more you live. Of course quitting is not an easy thing. If it were then everyone would do it, also what has to be taken into consideration is your quality of life, if you spend all your time smoke free but wishing you were smoking then it is no point to live a longer life that is filled with misery. That being said there are various options for quitting:
Will power alone
This is a tough way to stop smoking but can be done. Important is to reduce the temptation, so if you have particular places that you tend to want to smoke, e.g. when going out to drink, maybe it is time to change that, or if particular friends smoke it may be helpful to ask if they can help you out by not smoking around you. It also may help to physically set aside the money that you normally spend on cigarettes and allocate it for something fun for example a holiday to really show that your sacrifice is worth while.
E-cigarettes
These have the advantage that nicotine can be inhaled but without all the carcinogens associated with a standard cigarette, this can be an effective way to stop smoking. They also feed to ritual of smoking via holding of something in your hand as opposed to patches for example. Another advantage over standard cigarettes is that because they do not produce any fumes so there is no need to stand out in the rain when your craving hits.
Patches
Patches give you the nicotine in the form of a patch, the patch is applied to the skin and nicotine is delivered via the skin, some have had success with this method. It can get expensive though as the patches do not come cheap.
Chewing gum
The chewing gum gives nicotine via your mouth as you chew on it.
