Kids add years to your life.

According to a study of more than 1.4 million people published Monday in the Journal of Epidemiology & Community Health, parents live longer than adults without kids. “The risks of death were lower among those who had had at least one child than they were among those who were childless—and more so among men than among women,” the researchers concluded.

A 60-year old man with children will likely live a full two years longer than one without children, a woman of the same age with children will live 1 ½ years longer than one without, the study states.

“Childless people face support deficits … towards the end of life,” the researchers write. The study looked at all men and women living in Sweden born between 1911 and 1925, as well as their children.

Of course, being a parent isn’t all upside.  Parents experience more low points in their lives than non-parents (though they also experience more highs).  They also experience higher levels of stress.
