is your index finger longer or shorter than your ring finger? are you aggressive or not? you can find this article on google news.
well, if it is smaller than your pinky, then it is probably shorter than your ring finger and thus you should (according to the study) be more physically violent than the average person.
Hmm..At a relaxed state my index finger is barely smaller than my ring finger. A few millimeters of a difference. Must explain my complacence and my cowerdice.
