Okay, old man, put your hands on the home position of your computer keyboard. Your index fingers are the ones on the F and the J. Your middle fingers are on the D and the K. Your ring fingers are the ones on the S and the L. Your pinkies are on the A and the :. Your thumbs are the ones on the space bar.
Ring is slightly longer. Can streatch my index longer than my middle without bending it though. Can also pop my pinky back so that it almost touches the back of my hand. Freaks people out.
