My ring finger is about two and a half millimetres longer than my index finger

ScienceDirect - Biological Psychology : Finger length ratio (2D:4D) correlates with physical aggression in men but not in women

Who knew? There's a chance that if you're male, and have a really short index finger, you're the Clint Eastwood/Rambo type.

I'm not sure what my relative finger ratio is. By the look of it though, I should be a good candidate for singing "Give Peace a Chance" at rallies and Zen monkery. :-)
