I wonder if having a larger scar wouldn’t actually fortify President Obama’s profile, as he contends with Kim Jong Il, Mahmoud Ahmadinejad or Vladimir Putin. Imagine a president with a gnarly, vivid scar telling the rulers of China, “Nice country ya’ got here. I’d hate to see something happen to it if you didn’t stop foolin’ around with the value of your currency. Know what I mean?”

As recent presidential injuries go, President Obama’s is almost valiant. His immediate predecessor, President George W. Bush, famously choked on a pretzel. President Bill Clinton tore a tendon stumbling on the steps of Greg Norman’s house after a round of golf.
