Electronic game makers are developing products that promote activity and physical action. The concept capitalizes on the popularity of the game Dance Dance Revolution, which requires participants to step on the panels of a platform according to the direction of lighted arrows, creating dance steps. Some schools even use the game in physical education classes (Ann Pleshette Murphy, "Games to Keep the Kids Active," USA Weekend, Dec. 14-16, 2007).

It's important to get exercise—and during the winter we are often confined mostly to indoor workouts. Yet as it gets warmer, getting some fresh-air exercise and discovering the better-than-virtual reality of the natural world can help promote good health as well as appreciation of God's incredible creation. Even in the winter we can spend time outdoors when it's not too cold.
