Last week Thursday, Rotarians and guests were encouraged to focus on their health and diets.  Mr. Charles Johnson went from Public Relations in the hotel industry to an exercise and fitness guru.  He is committed to men and women alike achieving optimal health. According to Mr. Johnson, this can be accomplished by making small changes to one's diet.  He insists that Bahamians are capable of avoiding diseases such as diabetes, high blood pressure, and cardiac complications.  Mr Johnson informed his audience that with a shift in our diets and exercise, Bahamians can improve their health.
