A new study reported in a medical magazine concludes that even smokers who reach their 70s are likely to live longer if they stop smoking. Researchers say that they have got some of the strongest evidence (*据) that it's never too late to stop smoking.

The study was based on a five-year follow-up of 7, 178 people over the age of 65 who lived in Boston, New Haven and Washington counties in Iowa. The report showed former smokers ran about the same risk of death from heart disease as those who never smoked. Women who stopped smoking faced about the same cancer-death risk as those who never smoked, but men who gave up smoking still had a 50% higher risk. The men's extra risk of cancer largely disappeared if they had not smoked for more than 20 years. The discovery does not agree with the widely-known belief that by the time smokers reach old age, their habit has already hurt them, and those who continue to live healthily are probably immune (有免疫力的) to the dangers of cigarettes.
