i'm no doctor

But if you'll allow me, I'd like to diagnose ailing dictator Fidel Castro based on this Reuters Photo (hey, it's as good as Frist with a VCR, no?).

Ah, yes. Just as I thought. After furiously scribbling in a notebook and making several quizzical gestures I have deduced that, clinically speaking, Senor Castro's got "the sads". Which, despite what "Cuba" says, is quite serious.
