A Living Story The saying “beauty is only skin deep” is used by the same readers who judge novels based on their covers. An unfamiliar book is meant to be read‚ reread‚ dog-eared‚ and annotated until its true beauty is unlocked. Much of that beauty is hidden between the lines in various symbols relatable to the reader. Only after experiencing and understanding modern symbolism can one fully appreciate the story in question. The epic Beowulf for example was simply an ancient poem until one scholar

Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater. According to the Professional Association of Diving Instructor (PADI)‚ a “DEEP DIVE” is considered to be anything from 18 meters (60 ft) to 30 meters (100 ft). A scuba diver moves around underwater by using swim-fins attached to the feet‚ however external propulsion can be provided by a diver propulsion vehicle. Scuba diving may be performed for a number of reasons; either for recreational purposes

and exchange of oxygen and carbon dioxidebetween an organism and the environment. In air-breathing vertebrates like human beings‚ respiration takes place in the respiratory organs called lungs. The passage of air into the lungs to supply the body with oxygen is known as inhalation‚ and the passage of air out of the lungs to expel carbon dioxide is known as exhalation; this process is collectively called breathing or ventilation. In humans and other mammals‚ the anatomical features of the respiratory

A characters intentions are not always seen instantaneously. To understand the full meaning of why someone might go out of their way to help another is not always in the kindness of their own heart. A more intense and complicated plot is behind the thoughts of a character named Beowulf. Everything he does always has a catch to it and requires

Coastal Erosion The beaches of North Carolina’s coastline face an ongoing threat: coastal erosion. Though mostly gradual and relatively unnoticeable over the course of a year or two‚ the rising sea level combined with a season of storms or hurricanes can cause anywhere from a few feet to hundreds of feet of this delicate shoreline being stripped away. Solutions are constantly being studied and discussed‚ but often‚ the solution to erosion can be just as damaging as erosion itself. While vacationers
