Fifty is a monumental birthday for every man, but when you’re the President of the United States you have more to reflect upon than the average citizen, and less opportunity to do so. We’ve all seen how horribly the leaders of our nation age during their years in office. W. went in looking spry and came out looking fatigued. President Obama already looks ready to retire (and probably will November of 2012). But, regardless of how you feel about his policies or the progress he hasn’t made, at least he made it to 50 and dropped one hit single.
