The study conducted by researchers at Ohio State University, states that the number of siblings we have can actually determine how long you stay married.
The
study had analyzed data collected from about 57,000 people in the United States between 1972 and 2012. Those who had more siblings (up to seven) also had lower odds of divorce. Each additional sibling a person has lowers the risk of divorce by two percent.
While the researchers didn't examine why having more siblings reduces
the likelihood of divorce, but one of the study's co-authors theorizes
that it might have something to do with the conflict resolution skills
that are learned in a larger family.
