Michael Schumacher returned to his family home at Gland on Tuesday, way ahead of the Christmas date set by doctors at a rehabilitation clinic in Lausanne. Although his wife Corinna, 45, and children Mick, 15, and Gina-Maria, 17, are ecstatic, it is understood he remains mute and unable to move apart from random flutterings of his eyelids. Schumacher, remains riddled with tubing, hooked up to complex machines that feed him, enable him to breathe for long periods of sleep, remove waste from his body and monitor vital signs
