1) It's Monday morning and while you are getting dressed, you're looking at yourself in the are getting dressed, you're looking at yourself in the mirror,' i'm too skinny. I'd like to put on a little weight and be a bit taller and more muscular,' you think.' I also wouldn't mind thicker hair, longer legs, better teeth and a smaller nose. Speaking of my nose, is that a pimple on it? Oh, here we go again! I can't go out. I can't stand people staring at me.'

2) Do these remarks sound familiar? Almost everyone would like to change something about their bodies. Teenagers feel that way quite often because their bodies change while they are growing up. As you body changes, so does the way you feel about your physical appearance. Your body image often affects the opinion you have of yourself.

3) As body matures, you may think that it draws attention to you, and you may feel uncomfortable. You may also compare yourself to your friends to see if you are 'normal'. But growing up doesn't happen at the same speed for everyone. Girls usually start changing sooner than boys. Sometimes, they suddenly put on weght as their bodies need fat to grow. On the other hand, boys notice their voices getting deeper. These changes usually take place over two to five years.
