As authors, we are always looking for unique ways to make our stories stand out. One way to achieve that is to weave weird facts into the story line. Here are a couple to show you what I mean.
First, persons with a go-getter personality — dominated by ambition, logic and decisiveness — are likely to have a ring finger that is longer than his or her index finger. Why? The long fourth finger is an indication that this person was exposed to a higher than average amount of testosterone en utero, according to author Dr. John T. Manning of Rutgers University. He covers the subject in his book Digit Ratio.
Second, women change their taste in men based on their hormone levels. Researcher Tony Little found that women taking birth control pills tend to choose men with pronounced masculine features. The manly traits indicate a higher testosterone level, which is also linked to aggressive behavior and a higher than average likelihood of divorce.
Finally, an adrenaline rush can make the sparks fly between partners. Research by Arthur Aron and Donald Dutton prove it. They found doing something daring together increases the odds of bonding with your date. In one study, male subjects were asked to cross either a shaky or sturdy bridge to speak to an attractive female “researcher” who provided the male subject her phone number. Those men who met the female after the shaky bridge crossing were more likely to follow-up with a phone call and an invitation to go out together. The exhilaration of being in a risky situation together increases attraction.
