The MailOnline reports that a new research study at the University of Mainz in Germany suggests men with long ring fingers are more likely to drive too fast, overtake on dangerous roads and park illegally, and that such bad driving may be programmed from birth because finger length is directly associated with exposure to the hormone testosterone in the womb. The study also found that woman with low testosterone levels tended to have shorter ring fingers, and have poor spatial skills, such as map reading and the ability to park properly.
