I happen to know that Admiral Allen doesn't sleep a whole lot, but he looks here like he's gotten less sleep than usual.
Or perhaps he has the weight of the USA on his shoulders knowing that he's much in the public eye.
I somehow doubt that he'd be losing sleep in order to save the bacon of you-know-who and you-know-who. I think he's losing sleep trying to save the Gulf coast. He is a true dedicated servant for the public good.
Perhaps he's not getting as much sleep as usual, but he's as sharp as ever. Admiral Allen is one of the brightest people I know; and Admiral Allen is one of the most direct leaders I've ever met.
