Couples who both drink wine have a higher chance of a happy marriage in the long term. This according to a study published in the Journals of Gerontology. During this study, over 2 700 heterosexual American couples were followed as part of a long-term health survey. What did they find? If both couples drank alcohol, they tended to report a happier marriage over time. Women, it was reported, were the least happy in a marriage where they didn’t drink while their husband did. If both partners were teetotalers, this was also better than a marriage where one partner drinks and the other doesn’t. Lead researcher Kira Birditt says she’s not sure why alcohol had an effect, but that it might have something to do with the theory that couples who do more together tend to be happier.
