Ever wonder why Sheryl Swoopes was a successful athlete but, say, Kordell Stewart was not? According to a study by King's College London — whatever that is — it's because women with long fingers make better athletes than women with shorter fingers.
Actually, it's not just any finger: It's the ring finger. When the ring finger is demonstrably longer than the index finger, they tend to run faster.
Now, you might be looking at your ring finger right now and saying, "Hey: My ring finger IS longer than my index finger." This is because you are a male. If you're a woman, and you're not particularly athletic, your ring finger is likely shorter. Also, if your hand is bigger than your face, you have cancer — SMACK!
Also attributable to woman being able to run faster: Lots and lots of steroids.
