@Sabin: "DJS, is that happier if he's taller laying down or standing up?"
FUNNY! If you keep making wise-ass comments like this, I will be forced to consider you for membership into the exclusive Wise-Ass Club, of which I am the CEO and Alpha. You can replace And Don't Call Me Shirley - a former member I miss terribly who apparently lost a battle with the Forum Alpha (Simon).
The study didn't say. Girls????
However, on an empirical note, I can find no data suggesting taller men are better husbands, lovers or fathers. But based on a number of US studies, including a recent study by Harvard U and a poll of Fortune 500 companies about the height of their CEOs, men at least 6' tall make nearly $6k more per year on average than men who are 5'5" and the average height of male CEOs was 3 inches taller than the average male.
This suggests what we would intuitively expect: women place a high value on security, typically represented by power (height, fame, etc.) and $$$. Taller men make more $$ on average, as they likely do in S. Korea. This even has a name: Tall Male Syndrome.
Women will often select a male that will: earn more money, be a better protector, or otherwise stay close to the nest. In other words, anything that will give her that sense of security. Based on how we evolved and societal and cultural reinforcements, this makes sense. But what the S. Korean study suggests is that women will STAY with a man, when all other factors appear equal, who makes more money.
