The Finger of Destiny - before you run to get a ruler, let’s take a further look

While just surfing abroad, being the internet nerd that I normally am, I came across this very interesting study on human hands and the research ascribed to those findings. Measures are always relative to something in our society, but I never thought fingers had so much to do with how people's behaviors could be predicted. In this case, it’s the second digit — the index finger. They call this indicator the 2D:4D. This ratio is set before birth and stays with us throughout life. Those with the longer fourth digit relative to the second often display rapid-fire execution ability. (See also: aggression, fertility, confidence, and sporting ability).
