Where Did The Saying "Happy Wife Happy Life" Come From? No one seems to know where the adage "happy wife happy life" came from. There are some early mentions of it from plays, and many people believe it started from a real estate ad. While we might not ever really know where it came from, there's no denying that many people believe it to be true. And, the way that most people understand the saying "happy wife happy life" is that if you want your life to be good as a husband, you better make sure to do whatever you have to keep your wife happy. Why This Saying "Happy Wife Happy Life" Could Be True? There are plenty of theories on why the saying "Happy wife, happy life" could be true. One of the beliefs is that if a wife is happy, she will be more willing to do things to help her husband be happy as well. For example, a happy wife might look for ways to help and assist her husband. And, her good mood is much nicer to spend time with than a wife that's unhappy, sad, or indifferent. A Rutgers study found what they believe is proof that the adage is true. They questioned couples on their overall happiness levels within their marriage and also within other areas of their life. They found a correlation between the two, for both the husband and the wife. However, they did find that if the husband were sick, the wife's happiness level declined more, and the same didn't appear to be true for the husband.
