A University of Alberta study finds that measuring a man's index finger length relative to his ring finger length predicts his predisposition to being physically aggressive.
The shorter the index finger relative to the ring finger, the higher the amount of prenatal testosterone and the more likely the man will be physically aggressive, they researchers say.

The thumb--everything you ever wanted to know is all in the thumb. Personally, I've found the size of the thumb never lies. ;-)
hmmmm, that gives a new twist to the expression "all thumbs" lol
OMG, this is fascinating.
But what does it mean if you have a bent fifth finger?
My index finger is slightly shorter (about 2 mm) than my ring finger. Does this mean I encourage the agression of others?
