We're less than two months away from President Barack Obama's White House tenure coming to an end. So it seems like a good time to see what the stress of being the leader of the free world will do to a guy.

In this GIF put together by the minds at healthtrends (which is currently undergoing a redesign), you can see Obama morph from kid to POTUS to outgoing POTUS in seconds.

Besides being hypnotic, the loop also shows how quickly being president can age a person. In the last few frames, you can almost follow the progress of his gridlock battle with Congress as his hair gets grayer and grayer and the lines on his face get deeper.

Of course, the stress of the presidency changing the office holder's appearance is part of the job. But this just puts the transition into an easy-to-see form.

You sure you want this, Donald?
