The Checkup: Businessweek Projects How Obama Will Age Over Next Four Years

• Looks like the art department over at Bloomberg Businessweek had some fun with Photoshop recently.

I know there are scores of presidential before-and-after pictures to show that, yes, being president of the United States does age a person, but good lord this seems excessive. What do you guys think? (Oh and also? Click over to see the never-to-hit-newsstands cover of an aged President Romney, which Businessweek had at the ready if Mitt Romney won the election.
