You’re having a quiet drink in your favorite local pub. Near you is a biker dude in full regalia – chains, leather, etc. – chugging down large quantities of brew and with an angry scowl on his face. Also nearby is a solitary guy who looks like a clone of Bill Gates, very shy and introverted. He’s also drinking heavily but his demeanor suggests he wouldn’t hurt a fly. Which one do you think is about to explode into a violent, dangerous rage? If you’re answer is the biker dude, you’d be wrong....
