If your nails have taken a beating along with the economy, you might be able to blame your genes for desperately needing a manicure. Nail-biting nerves are genetic, according to new research — the study showed that a person's ability to deal with market turmoil is linked to her DNA.
Subjects' DNA was tested for variations of serotonin and dopamine which are thought to be impact risk-taking behavior, and the data was used to identify individuals with high-risk profiles or high-anxiety profiles. The participants were given money and told to invest it however they wanted, and the previously identified high-anxiety individuals invested 28 percent less money in risky investments than their high-risk peers.
Still, researcher Camelia Kuhnen acknowledged that experience has a lot to do with how much risk a person can handle and said, "People may learn a lot from this crisis."
