As a third-grader in Winsted, Connecticut, last year, Matthew Asselin was sick -- a lot. He was lethargic and plagued with a persistent wet cough, respiratory infections and painful headaches. As the school year wound down, Matthew's health worsened. In all, Matthew missed 53 days of school. But over the summer, a strange thing happened. Matthew was healthy. He was energetic. "When we put him back in school this year, within three weeks, he missed 10 days with a respiratory infection," Melissa Asselin said. That's when she had an a-ha moment. "When he was out of school, he was well. When he was in school, he became ill," Asselin said. Matthew's parents concluded that the 9-year-old's school, Hinsdale Elementary, was making their son sick.
