Why does Barack Obama look like a teenager?

[Dremmer]

He's 49 years old.

Because he is really only 19years old, thats why the big controversy over his birth certificate.
Everything before 1991 was faked by a conspiracy involving major league baseball.

But as with most presidents, he looks like he's hyper-aged the past two years.

Could it be that he unwinds and exercises frequently with pick-up basketball games?
