Can lungs heal after 40 years of smoking?

Why do some smokers have healthy lungs?

The mystery of why some people appear to have healthy lungs despite a lifetime of smoking has been explained by UK scientists. The analysis of more than 50,000 people showed favourable mutations in people's DNA enhanced lung function and masked the deadly impact of smoking.
