     Marriages improve after children grow up and move out,according to an academic study,which

suggests an "empty nest" is not always a bad thing.

     Popular wisdom has it that parents' relationships may suffer once their young fly the coop,because

they feel they have lost their purpose in life.However,a new study by researchers at the University of

California,Berkeley,has found that many couples actually feel happier when their children leave home

because they are able to enjoy spending time together.

     In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their

satisfaction levels shortly after marrying,when they were bringing up babies,once their children reached

their teenage years and finally at age 61,when almost all had "empty nests".

     Although not all said they were happier in general,most claimed their marriages had improved since

their children had left home.Researchers believe this is not just because the spouses were spending more

time together,but because they were able to enjoy each other's company more.

     One of the participants in the study,which is published in the journal Psychological Science,said:"

Once the kids grow up...there's some of that stress removed...that responsibility removed,so things are

a little more relaxed."

    Psychologist Sara Gorchoff,who carried out the investigation,said:"The takehome message for

couples with young children is 'hang in there'. " Her coauthor Oliver John added:"Don't wait until your

kids leave home to schedule quality time with your partner."

     However,Dr Dorothy Rowe,from the British Psychological Society,said the effects of living in an

"empty nest" will depend on the parents' relationship with their children."If you're just waiting for them

to leave home so you can get on with your life,then of course you'll be pleased to see them go," she said,

"But if you've built your life around your children you'll be terribly lonely.For some parents,their world

falls apart when their children leave."
