Your index and ring fingers length can affect your voluntary exercise desire.  According to a recently published paper, people who have higher index:ring finger ratios are more willing to exercise.  Generally women have higher ratio than men.  The study revealed a strong correlation between the digit length and levels of prenatal stress hormones as well, which ultimately affects one’s personality.  This research reminds me of the Chinese palmistry, which use the lines on the hand as well as the shape of the hand, to study one’s life, behaviour, personality, etc.
