The principle of happiness. Invest in children when you are young and gain in happiness when you are old
A study by Rachel Margolis and Mikko Myrskylä now sheds new light on that paradox: All around the globe, young parents are unhappier than young adults without children. At older ages, however, the association reverses and the existence of children in these later years brings greater happiness. Moreover, how strongly children affect happiness is influenced by the type of welfare regime in the respective countries.
