People who pursue degrees in psychology have far more options than just working directly with patients.

One example came from the Medical College of Georgia this week, where researchers have just completed a study on the importance of exercise for children. The study measured the benefits of exercise in fighting depression and improving self esteem among otherwise sedentary and overweight children aged 7-11.

"If you feel better about yourself, maybe you are going to do better in school, maybe you are going to pay more attention," Dr. Karen Petty said in a statement. Petty indicated that while many of the participants did not lose weight during the study, they experienced more emotional well-being and were on track to become less at risk for conditions like diabetes.

The Bureau of Labor Statistics notes that problems such as obesity and alcoholism, combined with a growing awareness of the importance of preventive care, could help fuel demand for clinical and counseling psychologists.

Overall, the BLS expects a 15 percent jump in demand for psychologists between now and 2016, faster than average compared to other industries.
