Everybody, especially smokers, wondered how some smokers experience old age and good health in old age, others die much younger. The answer, it seems, lies in the genes.
Worldwide annually as a result of cigarettes kill nearly 6 million people. However, the health of a certain proportion of smokers cigarettes have no effect. Studying them longtime smokers and their health and habits, scientists noticed that most of them have happened variation of certain genes, which called “longevity genes”.
This evolutionary mutation enables them to be resistant to pollution and other negative influences, and thus also harmful substances from cigarettes.
They explain it as a kind of extra care of their bodies.
– We found that certain genetic markers jointly promote longevity.
These are the same genes found in people who have experienced a profound one, and work so that allow cells faster to recover from the negative bio chemical effects, although repeatedly exposed to them, explained the author of the study, Dr. Morgan Levin of the University UCLA .
