Southpaw Presidents

I just read in an article that although only about 10% of people are left-handed, President Obama is now the 8th left-handed president out of 43 (He is the 44th president of the US, but Grover Cleveland was both the 22nd and the 24th!).

Every president since 1974 except for Jimmy Carter and George W. Bush has been left-handed (FYI, these would be Gerald Ford, Ronald Reagan, George H.W. Bush, Bill Clinton, and Barack Obama).  John McCain and Al Gore are also lefties.

"Some evolutionary advantage, whether overall greater intelligence or language skills, has kept a stable group of lefties for at least the past 200,000 years," said Chris McManus, professor of psychology and medical education at University College London.

I guess this kind of stuff is consistent with what everyone tells me -- that a disproportionately high percentage of mathematicians and other intellectuals are left-handed.  I wish I were a leftie!
