Jack Everett sat on his living room couch wearing a back brace, eyes glued to a massive TV set playing his favorite video game, NHL 2013.
"I'm the Boston Bruins," the 10-year-old said as he deftly worked the video controls. "The guy that just shot was Milan Lucic. He's a really good guy on our team."

"Well, I can eat lunch with friends, and I play cards," Jack says. But his classmates are out running and jumping outside.
