Researchers at the University of Cambridge in England report that men with longer ring fingers, compared to their index fingers, tended to be more successful in the frantic high-frequency trading in the London financial district.
The length ratio between those two fingers is determined during the development of the fetus and the relatively longer ring finger indicates greater exposure to the male hormone androgen, the researchers noted.
Previous studies have found that such exposure can lead to increased confidence, risk preferences, search persistence, heightened vigilance and quickened reaction times.
But you can be anything you wanna be, honest. Just click your shoes three times and repeat the wish in your head, and the tooth fairy will take care of it.
