The Chicago Tribune/Naperville Sun reports:

Naperville Student Survey: 70% of Teens are stressed, 50% don't talk about it. 

"Seven of 10 seventh-graders and nearly eight in 10 high school sophomores say they experience moderate or high levels of daily stress. About half of both groups say the stress makes it difficult to perform daily tasks because they're overwhelmed by anxiety and they lack focus and the ability to concentrate."
