The Importance of a Smile

I read recently that people who smile when being interviewed for a job significantly increase the likelihood of being hired. Interesting.

Also... People who sing while they drive lessen the likelihood of experiencing road rage by 75 percent.

Also... Las Vegas Black Jack dealers who smile while dealing bring in 5 percent more revenue than those who don't. The writer believes that it's because the players feel that the dealer is on their side when the dealer smiles.
