Smoking cuts life span by nearly five years: study
Smoking cigarettes has the same effect as cutting the life span by close to five years, according to a mortality risk chart released Tuesday in the US Journal of the National Cancer Institute. "The effect of smoking on the chance of dying is similar to the effect of adding five to 10 years of age," the study said. "For both men and women, smoking increases the risk of death by nearly the same magnitude as adding five years to a person's age."
