Know what the length of the finger means

According to research published in Behavioral Brain Research, there could be a link between index and proportion of ring finger and mental abilities. The ratio between the index and the index can be calculated by dividing its lengths. If the ratio is low, the person is likely to be strong and active. If they are high, we have better abilities in verbal memory tasks. Scientists claim that the length of the index is determined by the level of testosterone, which can affect spatial cognition. However, these generalizations are not universal.
