In High-Stakes Stock Trading, Finger Length Matters

For all those whose ring finger far outstretches their index finger, British researchers have pinpointed the perfect job: high-volume stock trader.
According to a new study, having a relatively long ring finger augurs well for success in those high-stress financial arenas where fast thinking, good reflexes and good old-fashioned guts matter most. A lengthy fourth digit, the authors note, indicates greater exposure to testosterone in the womb, which in turn gives what they call "high-frequency" traders a biological leg up by encouraging the development of the right mix of mental attitude and physical skills for making money in a cutthroat business.
