I think the second finger is ring finger and 4th is index ("Mr. Pointer").
Second finger is your index finger (next to thumb) and 4th is ring finger. My 2nd is much smaller than the 4th and I have aggression problems, at times.
I guess Juanita Broderick should have checked out Bubba's hands when she met him.
This article explains it better. I think this "linked" and "predict" stuff is bogus. Do they even know how testosterone levels influence the finger length? BTW, my ring finger is longer than my index finger. Should I go and beat my wife or something?
