Research has found that people who quit smoking drastically reduce their risk of dying from a smoking-related disease. Those who quit before they turn 51 cut their chances of dying within the next 15 years in half, as compared with people who don’t quit. Even smokers who stop in their sixties increase their life expectancy by one year. When you quit smoking, you live longer and those extra years are spent in better health.
