Benefits of smiling, from Dr. Catania

People with big, happy smiles may live than those who don’t, after all. That, according to a new study at Wayne State University.

Dr. Catania has known for a long time that positive emotion has been linked to both physical and mental health, but researchers there used information from the Baseball Register to look at photos of 230 ball-players who began their careers in baseball before 1950. The players' photos were enlarged, and researchers studied their smile intensity (ranging from big smile, no smile or partial smile).

The players' smile ratings were then compared with data from deaths that occurred from 2006 through 2009. The researchers then corrected their analysis to account for other factors associated with longevity, such as body mass index, or BMI, career length and college attendance. The researchers found that players who weren't smiling died at the average age of 72.9 years. Players with partial smiles lived to be 75. Those with big smiles, however, lived on average to be 79.9 years old.

The take-away from the new study? Smile now, smile often and you might just live longer! Have you been perfecting your smile by visiting the office of Joseph Catania regularly? If not, give us a call!
