A Byzantine emperor described the Beserkers as being possessed by a ferocity and madness seen only in wild beasts. It’s where the word ‘beserk’ came from. Have a look at the palms of your hands. Are they hairy? If so, then perhaps it’s a sign. Do you always leave your left thumbnail uncut – so it looks like a claw? Do you have a tattoo of a crescent moon, somewhere on your body, and very long third fingers on each hand? Do your eyebrows meet in the middle, on the bridge of your nose, and do you find it impossible to sleep with your mouth open?
