Relationship Facts.

9. Divorce may be contagious.

We don’t want to ruin your double date plans but the people you surround yourself with matter quite a bit. A study published in the “Social Forces” Journal in 2013 found that divorce can work like a social contagion, spreading among friends and families. If someone in your social network ― say your coworker BFF or family friend ― splits up, the statistical likelihood of ending up in divorce court yourself increases by 75 percent.

As the researcher explained, “Individuals who get divorced may influence not only their friends, but also their friends’ friends as the propensity to divorce spreads.”

10. Marriage is good for your heart.

The jury is still out on whether single people or couples are healthier, but research suggests getting hitched is at least heart healthy.

In one recent study out of New York University’s Lagone Medical Center, researchers found that married men and women had a five percent lower chance of cardiovascular disease compared to single folks.

Why’s that? It may be because married people have better emotional support and deeper social ties to family, which in turn produces lower blood pressure and general heart health.
