As it turns out, there’s more to risk than Princess Peach’s freedom when playing video games—you can also risk your health. Researchers at UNICEF and Domestos found that there were 7,863 germs crawling over every 100 square centimeters of your game controller. Luckily, it's a cinch to blast away germs from this grimy surface. Just remove the batteries from the controller, scrub the crevices with a dry toothbrush. Then wet a cloth with a mixture of water and rubbing alcohol and rub lightly over the surface of the controller to sanitize.
