While only between 10 and 15 percent of the global population identifies as being left-handed, a seemingly disproportionate number of world leaders, artists and icons live their lives southpaw style. Take, for example, U.S. presidents.
President Obama is a proud lefty and he's far from alone. In fact, five of the United States' last seven presidents favored the less favored hand: President Clinton, President George H.W. Bush, President Reagan and President Ford.
Interestingly enough, Senator John McCain is also left-handed. So either way the 2004 election had gone, a lefty would have been Commander-in-Chief.
