Of particular interest would be articles of information on the person(s), type environment, location, social class, etc. The overall desire is to know if this disorder affects more people that live in areas where more dark hours are prevalant over light hours or does it apply largely to people who are more used to daylight and sunny hours versus dark and dreary hours.
