New data confirms the obvious

It's never too late to quit smoking, and researchers have new data to prove it. Even at the age of 64, kicking the habit can add four years to a person's life, while quitting by age 34 can increase life expectancy by a decade, according to a study published online yesterday by the New England Journal of Medicine. After analyzing health data from more than 200,000 Americans, researchers calculated that current smokers were three times more likely to die during the course of the study compared with people who had never smoked. For the most part, their deaths were caused by smoking-related ailments, including heart and lung disease. Overall, their odds of surviving to age 80 were half as good as for never-smokers. But the study, one of two large-scale surveys in the journal providing updated information on smoking and mortality, saw significant benefits for those who quit. Giving up smoking between the ages of 35 and 44 was associated with a gain of nine years of life, and those who quit between 45 and 54 lived an extra six years. With this in mind, I'm sure a lot of older people will decide they can still quit and get a few years' more life expectancy in return. In fact, people shouldn't even be smoking in the first place because it's just filthy.
