(沧州模拟)All of us know that smoking does harm to our health. But do you think everything will be OK as long as you stop smoking?
Unluckily, the answer is NO. New research has found that even if you give up smoking, the damage it has done to your genes(基因) will stay there for a much longer time.
In the research, a team of American scientists studied the blood of 16 000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7 000 genes of smokers had changed—a number that is one-third of known human genes.

According to news reports, both heart disease and cancer are caused by genetic changes. Some people might have had the changes when they were born, but most people get them in their daily lives while doing things like smoking.
When you stop smoking, a lot of these genes will return to normal within five years. This means your body is trying to heal(治愈) itself. But the changes in some of the genes can stay for as long as 30 years. It’s like leaving a footprint on wet cement(水泥)—it will always be there, even when you’ve walked away and when the cement becomes dry.
