"Happy wife, happy life" isn't just a cliché dads tell their sons on their wedding day.  Science just PROVED it.

We've all heard the saying also phrased, 'If Momma ain't happy, ain't nobody happy', but it looks like science just confirmed it. In a new study from Rutgers University, boffins found that the biggest key to a happy marriage, is how happy the WOMAN is.

If she's happy, her husband tends to be happier too.  And if she's UNhappy, her husband tends to be unhappy too.  It's very rare that there's a couple where the husband is satisfied and happy in the marriage and his wife isn't.

The researchers say, quote, "When a wife is satisfied with the marriage, she tends to do a lot more for her husband, which has a positive effect on his life."
