Finger Size Does Matter … In Sports

New studies suggest the size of two fingers could predict athletic ability.

Examine your fingers. Which one is longer? Is it the index finger (the finger you use to point with — technically the second digit, or 2D, counting the thumb) or the ring finger (the fourth digit, or 4D)?

The relative length of the index and ring fingers is known as the digit ratio or the 2D:4D. For example, if your index finger is 2.9 inches (or 7.4 cm) long, and your ring finger is 3.1 inches (or 7.9 cm) long, your digit ratio is 0.935 (i.e., 2.9/3.1 or 7.4/7.9).
