New Delhi, Nov 25 (ANI): In an attempt to find the magic formula for keeping a marriage healthy, researchers conducted a study that seems to signal greater marriage satisfaction. Robert Levenson, director of the Institute of Personality and Social Research at the University of California, Berkeley, who has been studying 156 couples since 1989, has suggested that women may hold the key to resolving arguments. It was found that relationships in which the wives cooled down quickly after an argument were the happiest in both the short and long term.
