Protective genes found to promote longevity

Some people have "protective genes" that allow them to live well past 100.

"Supercenturians" are people who live to be 110 or older and are extremely rare.

In a new study, U.S. scientists found evidence that genetics play a major role in living so long.

Although they have as many disease-related genes as everyone else, researchers found that supercenturians may have longevity-associated variants that cancel out bad genes.
