Some physicians are saying that being anorexic is becoming contagious among your people today, guys as well as girls.  The teen years are focused on physical changes and appearance is everything during your teen years.   Girls worry about weight gain and see themselves as always being too fat.  Guys think that they need to look muscular and athletic, and must be in shape and strong.   When you are in an environment where the majority of your peers are afraid to eat, and need to project a thin image to fit in to their particular social group; it is easy to begin bad habits that will hurt you, in order to achieve the look of a 90 pound person.  It does not help that images we see on everything from TV to the movies, to magazine ads, perpetuate the myth that thin is always in.  IF your idea of normal is weighing 4 times a day, living on grapes and water, bingeing but then purging, and fearing the idea of eating a plate of nutritious food for fear of weight gain, then you are anorexic.
