A 2017 study surveyed over 8,000 participants and found that there’s a direct correlation between the ratio of a man's height to his wife’s and their marital happiness and satisfaction, meaning the taller you are than your wife, and the more inches you have separating you height-wise, the better your relationship will be.
Apparently this has lots to do with evolution, but our tall ladies with a man shorter than them might disagree! What do you think???
