Former Formula 1 chief doctor Dr Gary Hartstein has warned that fans must prepare themselves "for the worst" news as attempts to awaken Michael Schumacher continue following his horrific ski accident. Schumacher suffered serious brain injuries after hitting his head on a rock when skiing at the end of December, with attempts to bring him out of his medically-induced coma now in an eighth week.The 45-year-old's manager Sabine Kehm confirmed 13 days ago that attempts to awaken the seven-time world champion are continuing and will do for "as long as it takes", warning that it can be a very long and drawn out process. However, Dr Hartstein - who was a key figure in the paddock until the end of the 2012 season - has admitted that the longer it takes, the less likely it is that Schumacher will ever recover. TOI. Please lets not despair nd keep praying for him to recover fully....nothing is impossible.
