They say a happy wife means a happy life, but it seems that old adage could use some tweaking.

Couples with similar drinking habits are more likely to be happy with their relationships, a study from the University of Michigan has found.

In other words, a hop-happy wife may be the key to marriage bliss – but only if you’re enjoying a cold one right alongside her.

For the study – available online in Journals of Gerontology B: Psychological Sciences – researchers analyzed 2,767 couples that partook in the Health and Retirement Survey between 2006 and 2012. Participating couples were asked about their drinking habits – if they drank, how often and how much – along with any negative feelings they may harbor about their relationships. For example, they were quizzed on whether they perceived their partner as demanding, critical, unreliable or irritating.  

The researchers found that couples with the same drinking habits – either both drinkers or both sober – were less likely to have negative feelings about their marriage than couples where only one partner drank.

Curiously, couples featuring a drinking wife and a sober husband were more likely to become unsatisfied with their relationships over time.

All this said, study author Kira Birditt stresses that couples shouldn’t necessarily up their drinking habits in hopes of improving a relationship. She does, however, recommend staying sober when your partner does – which can be easier said than done, but could apparently work wonders in the long run.
