Parenthood the key to longevity

Being a parent may sometimes feel like it's sending you to an early grave but your children could be the key to living longer, new research suggests.

A Swedish study published in the Journal of Epidemiology & Community Health found parenthood is associated with a longer life than childlessness, particularly in older age, when health and capacity start to decline.

The difference in life expectancy may be as much as two years.

Researchers at the Karolinska Institutet, Stockholm tracked the life span of more than 1.4 million men and women over 60 living in Sweden and born between 1911-1925.
