Very interesting studies to say the least, but I'm somewhat confused. So the bigger the difference between the index and ring finger the more T exposure in the womb and thus translates to better fertility. They also state that a short index finger the higher the aggression, but what about the ratio?
Most importantly how do you measure finger length? I'm measuring from the knuckle because otherwise my index fingers are 1 inch shorter than the ring fingers do a lot of boxing and striking. Left ring finger is +.6" and right ring is +.45" so I should have higher T and increased aggression? The latter holds true but not the first unless that only indicates exposure in the womb. I should also have decreased heart risks but family history indicates otherwise.
