This from Yahoo News:
"Researchers at the University of Groningen in the Netherlands and University of Valencia in Spain asked 549 Dutch and Spanish men and women to rate how jealous they felt, and to list the qualities in a romantic competitor that were most likely to make them ill at ease.
Men generally felt most nervous about attractive, rich and strong rivals.
But these feelings were increasingly relaxed the taller they were themselves. The more vertically challenged the man, the greater his feelings of jealousy."
Makes sense to me it is all about confidence. A man who is tall I am sure feels more confident. Same goes for women if you think about it, high heels.
