The mystery of people appear to have healthy lungs despite a lifetime of smoking, explained by UK scientists

The examination of more than 50,000 individuals indicated ideal transformations in individuals' DNA-upgraded lung work and conceal the savage effect of smoking. The Medical Research Council researchers say the discoveries could prompt new medications to enhance lung capacity. In any case, not smoking will dependably be the best choice, they say. Numerous, yet not all, smokers will create lung sickness. In any case so too will some who have never touched a cigarette in their lives. The analysts broke down the tremendous sum measure of wellbeing and hereditary information from volunteers to the UK's Biobank project.They took a gander at Chronic Obstructive Pulmonary Disease (COPD) which prompts shortness of breath, hacking and rehash mid-section contaminations. The condition is thought to influence three million individuals in the UK and incorporates illnesses, for example, bronchitis and emphysema. By contrasting smokers and non-smokers and those with the illness and without they found areas of our DNA that lessen the danger of COPD. 

So smokers with "great qualities" had a lower danger of COPD

 than those with "awful genes".Prof Martin Tobin, one of the scientists at the University of Leicester, said the qualities appeared to influence the way the lungs develop and react to damage. The habit also increases the risk of heart disease and cancers, which are not considered in this study. The scientists also uncovered parts of the genetic code which were more common in smokers than non-smokers. They seem to alter the brain's function and how easily someone can become addicted to nicotine, although that still needs to be confirmed. Prof Tobin said the findings offered "fantastic new clues about how the body works that we really had little idea about before and it's those things that are likely to lead to some really exciting breakthroughs for drug development."

Their findings were presented at a meeting of the European Respiratory Society and published in the Lancet Respiratory Medicine journal. Ian Jarrold, the head of research at the British Lung Foundation, said: "These findings represent a significant step forward in helping us achieve a clearer picture about the fascinating and intricate reality of lung health.

"Understanding genetic predisposition is essential in not only helping us develop new treatments for people with lung disease but also in teaching otherwise healthy people how to better take care of their lungs."
