Do you want to live a little longer? Get a second wife. New research suggests that men from polygamous cultures outlive those from monogamous ones.
After accounting for socioeconomic differences, men aged over 60 from 140 countries that practice polygamy to varying degrees lived on average 12% longer than men from 49 mostly monogamous nations, says Virpi Lummaa, an ecologist at the University of Sheffield, UK.
Lummaa presented her findings last week at the International Society for Behavioral Ecology's annual meeting in Ithaca, New York.
Rather than a call to polygamy, the research might solve a long-standing puzzle in human biology: Why do men live so long?
