For example, I thought this article about Obama's left-handedness was interesting. Apparently, a disproportionate number of lefties have been President, when compared to the general population. (As a side note, probably 30% of my friends are left-handed, which is sort of weird.)"...So while right-handed people usually process language exclusively in the left side of their brain, lefties process language mostly in the right but partly on the left as well. That preferential wiring may make lefties more adept at certain skills required for leadership."
I wondered if that made us more adept at skills required for other things, too, and maybe it does:
"Some researchers claim that lefties are more intelligent and eloquent than their right-handed counterparts, and as a group have historically produced an above-average quota of high achievers. Left-handers' brains are structured differently in a way that widens their range of abilities. In tests conducted by Dr. Alan Searleman from St Lawrence University in New York, he found that left-handers can be considerably more intellectually gifted.
There were more left-handed people with IQs over 140 than right-handed people - which is the 'genius' bracket. This is perhaps why there are more "lefties" in creative professions - such as music, art and writing - and more left-handed astronauts and leaders than would be expected."
Well, duh. ;) I don't even know where I got the left-handed thing from, really. Only two other people since my great-grandparents have been lefties, on both sides (out of...well, I don't know, a lot). What can I say? I'm a freak.
