And this is not just from some random personality test created by some random people on some random site. It's backed by scientific research and is featured on television.

Some interesting facts:
Men generally have a ring finger that is longer than their index finger. Women's ring and index fingers are often of equal length.

Men are twice as likely to be left-handed as women.
