(Newser) – Boys with ring fingers longer than their middle fingers may be speedier than peers with more symmetrical hands, a study of Qatari adolescents suggests. The speed difference is associated with exposure to testosterone in the womb, LiveScience reports. Finger length can also predict men’s aggression and SAT math scores, women’s athletic ability, and risk of osteoarthritis in both genders, other studies have shown.
