Country singer Garth Brooks and American football star TROY AIKMAN have unveiled a playroom for sick patients at a U.S. hospital. The crooner and the former Dallas Cowboy visited children on Tuesday (15Jan07) at Cook Children's Medical Center in Fort Worth, Texas, where they opened an updated therapeutic playroom called the Zone Playroom, formerly known as Aikman's End Zone. Aikman says, "We wanted to do something for them because they spend all day in their bedrooms and we just wanted to get them out of there so they could have a little bit of fun."
