Sorry ladies the proof is in the index finger

According to a new study in Germany, women do have a natural disinclination towards reading maps and parking properly. Well those are just two everyday examples of special ability that the study says women with low testosterone have less spatial skills. Women's ring and index fingers are good indicators according to the study, those with equal fingers have more trouble, those with a longer ring finger less. Yes it's just one test but husbands are still going to rejoice everywhere.
