ing, it was sorted, categorized, and analyzed to determine whether it supported the theory that stress causes illness. The remainder of the information gathered for this project was in the form of both secondary and primary research – using the internet and the library.Findings/ResultsTwelve females and nine males responded to the 30 questionnaires that were distributed. The level of extroversion was the dividing point for the comparative analysis.
