Happy wife, happy life confirmed in study

There's some evidence behind the old saying - happy wife, happy life.

After talking to 400 long-time couples, a Rutgers sociologist found that the more content a wife is with a marriage, the happier a man feels about his overall life...

Not just the marriage.

The researcher says it may be because a woman who is happy in her marriage takes better care of her husband, boosting his overall health and well-being.
