Trends change with time, and teenagers are sensitive to trends. Things we use in daily life have varied across the ages. The alternation of things and trends are closely linked.
  We have more ample choices of Manga and magazines than before. Now there are many options for readers, and we can have more enjoyment and get more information we need.
  These days, we can carry our music. We can take our favorite songs and put them into a portable player. In this way, we can listen to music wherever we want.
Anyone in the old days could not imagine this high technology.
  Cell phones are the most readily available thing to us. Recently, it is hard to find a teenager who does not have a cell phone. Also, some elementary school students are given them by their parents for security. E-mail and phone calls are necessary to us for association with others.
   What we have for enjoyment are things that are necessary to have a fulfilling life.
