Most teens in America are either: fat, overweight, dumb, lazy, and disrespectful.





Teens in Japan, Europe, and other countries seem to be : hardworking, in shape, smart, and respectful.





Now I know not all American teens are like this, I know I'm not, but I've met a lot who are.
The ones that live here and other rich countries are more materialistic, the ones in poor countries hate life and always feel sad %26amp; pain, the ones in peaceful countries learn to appreciate life and each other, the ones that live in war ravaged countries learn how to survive.
