Sitting on exercise balls brings more than a smile to students and teachers.
Some fourth-graders at Conrad Weiser West Elementary School in Womelsdorf love their new chairs-—probably because they're not really chairs at all.
The kids are sitting on the air-filled balls. But different from those just for exercise, these have small legs that keep them from rolling. Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By using exercise balls instead of common chairs, teachers find students' posture(姿势) and attention improved.
Dotti Pownall, a fifth-grader teacher in West Virginia, has been using balls as chairs since December 2008. "The students love them." she says. Pownall took a survey of her students. She found that 80 percent, thought sitting on the balls helped them concentrate(专注) better:
"Besides, they’re fun,b" says Pownall.
According to WittFitt,b a company that has sold balls to more than 200 schools, they can improve kids' posture and classroom behavior.
Exercise ball chairs are getting popular in classrooms, from preschool to college. Some adults (成人) even use them at work.
Lisa Witt felt so strongly about the use of balls as chairs that she started WittFitt. She said the company not only encourages the use of balls but also educates teachers and students on how to use them. "We sell balls in 24 states in America, three provinces in Canada and Japan." says Witt.

Now and then we all get ill. Then we usually go to see a doctor. Doctors know a lot about what makes us ill. They may give us something to take. The medicine often makes us well again.

But sometimes the doctor’s medicine doesn’t work. A sick person does not get well. The pain will not go away. This happened to one man. He was in hospital, but he was not getting well. Then he found a new “doctor” inside himself. This “doctor” was his own sense of humor(幽默感). He saw funny films. He read funny books. And something wonderful happened. Laughing took away his pain. Then he was able to sleep and rest. His own happy feeling was his best “medicine”. His doctor thought so, too.

Another man was ill, and he had a terrible pain in his back. The doctors could not stop it from hurting. So the man began to “picture” his pain. In his head he “drew” a picture of a dog. He imagined it as a real dog. And he made friends with the dog. And his pain went away!

These stories may surprise you. But more and more people are getting well in this way. So visit the “doctor” inside you and you can stay happy and well.
