Jan.24 (GMM/Inautonews.com) It is completely open as to how long doctors will keep Michael Schumacher in his induced coma.

It is now approaching a month that the seven time world champion has been lying unconscious in a Grenoble hospital, following his late December skiing crash.

There are unconfirmed reports that the great German may never wake up, or that if he does he could be in a permanent vegetative state.

Germany’s Bild newspaper reports that “there is still no date set for when the doctors will wake him up from deep anaesthesia.”
