Who says that butterflies in the stomach are only for the young? A new study by psychologist Iris Wahring from the University of Vienna and her international team shows that when people over 50 enter into a new relationship and seal it by moving in together, their life satisfaction increases significantly. The study also challenges a common assumption: for couples who already live together, getting married later in life is not associated with a further increase in well-being on average. The findings were recently published in the International Journal of Behavioural Development.
