A common genetic mutation is linked to an increase in life span of about 10 years among men, researchers reported on Friday.

The mutation, described in the journal Science Advances, did not seem to have any effect on women. Still, it joins a short list of gene variants shown to influence human longevity.

By studying these genes, scientists may be able to design drugs to mimic their effects and slow aging. But the search for them has been slow and hard.

When it comes to how long we live, nurture holds powerful sway over nature. In 1875, for example, life expectancy in Germany was less than 39 years; today it is over 80.
