I figured that I was safe from the studies showing that first-born siblings are smarter than their younger brethren because my brother and I are both firstborn to our fathers. Sadly, though, the key difference comes not in biological factors, but in family dynamics. So it turns out he's smarter than me. Nuts.
Well, at least I'm better looking. And younger. And, according to the article, awesomer. "[Younger siblings] are more likely to participate in dangerous sports than eldest children, and more likely to travel to exotic places, studies find. They tend to be less conventional than firstborns, and some of the most provocative and influential figures in science spent their childhoods in the shadow of an older brother or sister."
