Every time you're hoping Dame Fortune smiles again, just wear your lucky charm. It actually works, a scientific study says.
In a German study, when volunteers used their key chain, special stone or sentimental jewelry, they did better at a computer memory game than those who didn't have anything special to hold onto, according to msnbc.com.
"Superstition increase people's confidence," the New York Daily News quoted study co-author Lysann Damisch as saying.
And the University of Cologne social psychologist added: "In other words, if you have your lucky charm close by, you feel more confident and secure about the following task, which makes you try harder and perform better."
Lucky charms may just boost your confidence enough that when you are in the midst of something scary, you may be more confident and at ease if you're wearing your favorite necklace.
