A Longer Life May Not Be in Your Genes

Long life spans tend to run in families, a phenomenon that's often attributed to people's genes. But now, a large new study of data from the genealogy website Ancestry reveals that genetics may play less of a role in life span than previously thought.

The reason? Previous studies failed to take into account a quirk of human relationships: that people tend select romantic partners with similar traits to their own. The findings mean that previous studies may have substantially overestimated the heritability of life span, the researchers said.


Diet, exercise, and lifestyle choices are much more important than your genes.
