Parenting is not an easy job, but the hard work may eventually pay off. Research demonstrates that parents have lower mortality rates in old age than childless men and women. Although this finding has been replicatedoften and in various settings, many questions still remain unanswered.
We need to understand the causal mechanisms behind the longer survival among parents, and during what point in life this survival advantage arises. Are mothers and fathers less likely to develop diseases? Or does the advantage arise because they survive longer once a disease occurs?
