Probably true

From The Daily Mail:

Parenthood makes people happier - but only after their offspring have moved out.

That's according to research from Germany's Heidelberg University which examined data from a recent European survey.

It asked 55,000 people about their emotional well-being and found happiness is more common among those aged 50 or above who have independent children.

Specifically, they were less likely to be depressed and have more financial stability than their childless peers.

In two years, I will be able to confirm to confirm the veracity of this or otherwise.

Last time I posted something along these lines, A K Haart commented that the joy is short lived - after a few years, your children dump their children on you.
