Michael Schumacher's wish to 'disappear' into a private life away from the media spotlight after his F1 career has led to the secrecy around his current condition.
Seven-time F1 world champion Schumacher has not been seen in public since his devastating and life-changing ski accident nine years ago.
The German legend suffered catastrophic injuries when he went off-piste and hit his head on a boulder while skiing in the French Alps with son Mick, then 14, in December 2013.
