A new study suggests that the length ratio between women’s second and fourth fingers is a good indicator of their sports ability. Researcher Tim Spector of St. Thomas’ Hospital in London and his colleagues analyzed hand X-rays from more than 600 female twins who also provided information on their sports abilities. They report their results in the British Journal of Sports Medicine. From The Independent:
The finding adds to evidence that the ratio between the two fingers – not the length itself but their length relative to each other – is associated with a number of different personality traits, which include sexuality, fertility, intelligence, aggressiveness and musical ability. The difference is believed to be linked to the level of the male hormone testosterone, to which the foetus is exposed in the womb. Scientists have suggested that the higher the level of testosterone, the more masculine the resulting foetus is likely to be, with its associated traits of strength, fertility and mathematical ability.
