Some say it’s trust. Others believe it’s humour.
However, it turns out that a woman’s happiness within a relationship is dependent on something rather more physical.
Yes, according to The Express, a study involving more than 7,000 women found that we tend to be happier with taller partners.
That’s right, it turns out that the bigger the height difference between you and your partner, the happier you are likely to be.
As for the reasoning behind this preference the researchers cannot be entirely certain (they did concede that the feeling wanes as the years go by).
Of course, every couple is different and we’re gonna go out on a limb and declare that a long-lasting relationship needs more than just a good height difference.
