Just in case you need a reminder - and you might - here's a list of the very best reasons to quit smoking.

Smoking decreases your life expectancy. According to the American Cancer Society, smoking decreases you life expectancy by an average of 10 to 12 years. Smokers between the ages of 35 and 70 have death rates three times higher than those of people who have never smoked.

Smoking dramatically increases your risks of developing certain cancers. These include lung cancer, mouth and throat cancer, pancreatic cancer, bladder cancer and liver cancer.

Smoking dramatically increases your risk of other serious health problems. These include heart disease, stroke, bronchitis and emphysema.

Cigarette smoke contains 4000 cancer-causing chemicals and 43 carcinogens. These include arsenic, a rat poison; benzene, a poisonous gas; polonium-210, and formaldehyde, also known as an embalming fluid.

Smoking increases your risk of blindness. According to the Journal of the American Medical Association (JAMA), people who smoke a pack a day more than double their risk of developing age-related macular degeneration, the leading cause of blindness in people over 65.

In men, smoking increases the risk of erectile dysfunction.

Smoking slows recovery. Not only are smokers more prone to illness thanks to increased free radical production and a loss of antioxidants, smoking also slows their recovery from illness, surgery, and slows the healing of wounds and broken bones.

Smoking increases your child's risk of developing illness. If you smoke in the house or around your children, they are more prone to develop asthma, bronchitis, pneumonia and other respiratory problems; ear infections; behavioral problems; and cancer later in life.

Plus, smoking increases the chance that your children will also become smokers

Smoking decreases your ability to do everyday things. As smoking decreases lung function, it can be harder to do everyday things like strenuous exercise or even climbing stairs and playing with children. For many smokers, the time in a restaurant or movie theater is just too long to go without smoking so they omit these activities from their lives.

Smoking costs A LOT of money. Four dollars per pack per day adds up pretty quickly. That's $28 a week, $112 a month, and $1344 a year. Imagine what you could do with an extra thousand dollars a year!
