Apparently he had gout so bad and so long that there's a stool in some museum somewhere that was acid damaged from the uric acid that leached out of his foot. (It helps slightly to elevate your foot when having an attack. )
I can't imagine how painful that must have been. No wonder he was a murderous tyrant.
Probably drove him nuts. Karma.
I used to love scallops and other shellfish (had your same attitude 25 years ago). Now I'm afraid to eat it.
