There are seven ways to divorce-proof your marriage.
Or is it in ten? Or five? Or perhaps it’s eight.
Whatever the number, economist Enrico Moretti from the University of California Berkeley has added another to the list: make sure your firstborn is a boy.
In a startling interview on Freakonomics Radio, Professor Moretti revealed that in marriages where the firstborn is a boy, there is less chance of the husband leaving the marriage.
‘Parents who have firstborn girls are significantly more likely to be divorced and parents who have firstborn boys are significantly more likely to stay together,’ he said.
