Girls on the Edge by Dr. Leonard Sax, focuses on the things that are causing a crisis for girls. The book cites sexual identity, the cyber bubble, obsessions and environmental toxins as the four main factors. The book is 272 pages and was published by Basic Books in July 2011 and sells for around $13 for a paperback copy or $20 for the hardcover edition. The book begins with an explanation of teenagers and how they are different from teenagers of 50 years ago. More and more teenagers are depressed and taking drugs. The author states that teenagers today take many more drugs than teenagers in the past. In the first part of the book, Dr. Sax discusses the four aforementioned factors that he believes are influencing girls' crisis. In the first chapter Dr. Sax discusses how girls are expected to be sexual beings at an earlier age than ever before. The main focus of this chapter is how the culture has shifted from a dating culture to a hookup culture. Sax explains how girls lose their virginity at an early age and become sexual objects earlier than ever. He claims this is the fault of the change in our culture. Contrast the songs "Paradise on the Dashboard Light" and "I kissed a girl". In the first song, written in the 1970s, a boy and a girl are getting intimate in a car when a girl stops everything and says, "Stop right there! I gotta know now! Before we go any further! Will you love me? Will you love me for always? Do you need me? Will you never leave me? Will you make me this happy for the rest of my life?" This is because in the 70s many girls would not have had relationships without the promise of marriage. In contrast, this last song is about... middle of the paper... how it's changed from 30-50 years ago.2) I've learned that girls establish a hierarchy at school differently than boys, so thinner. 3) I learned that girls have been proven to dress to impress boys and do many things, especially sexual things, to get attention or intimacy. 4) I learned that many things in life repress women's gender roles. These things include drinking, toys, clothes, and so on. 5) Finally, I learned that girls exclude people for many things. Music, sexual acts, not dating them, etc. They usually marginalize that person rather than using physical violence like kids do. Works CitedSax, Leonard.
