"How is Michael? How is Schumi?" is the favourite question that is buzzing everywhere.

The latest news is that he is finally showing some response to treatment. The seven-time Formula One world champion's ex-boss Luca Di Montezemolo said: "I'm very pleased to know that he is reacting. I know how strong he is. I'm sure that thanks to his determination, which will be crucial, he will come out from this very, very difficult situation. And I really hope."

Still, there is not much news, as the statement is again followed by silence. It leads to a number of questions and speculations about his real condition. There are fans who are praying fervently and asking regularly for updates.

No news is not always good news. In fact, it only raises more questions, rumours and speculations than is necessary.

Earlier, Schumacher's former manager Will Weber was eager to know about him, and even slammed his wife, Corinna, for preventing him from visiting him.

"I think Michael's fans would be happy if they were given an honest message about his condition. It would also help the people with whom Michael worked all these years better cope with the situation," he said.

Niki Lauda, chairman of Mercedes, asks the family to be more transparent about his health. "The family protects him and I understand that completely. But it means that all those who would like to know something, do not. I often think of him, but unfortunately, I have no contact. We all just hope, hope, hope," Lauda explained.

No one really knows what happened to him once he came out of a medically induced coma, almost three years since he had a skiing accident on Dec 29, 2013. He just fell and hit a rock while he was skiing off-piste in Meribel. After that, there is not much news about him.

Two years ago, Sabine Kehm, manager of Schumacher, put out a statement on behalf of his family: "Michael has left the CHU Grenoble to continue his long phase of rehabilitation."

However, she did not reveal much about him. "I think it was his secret dream to be able to do that (disappear) someday. That's why now I still want to protect his wishes in that I don't let anything get out," Kehm had mentioned.

So news about his rehabilitation is sporadic and rare, as he is screened from the media glare.

Once he slipped out of a medically induced coma  at the University Hospital Centre in Grenoble, he was then shifted from Grenoble to Lausanne to his family home in Lake Geneva. A number of specialists and private accommodation was in place for his sake.

The care and treatment every week costs $140,000 and is managed by 15 medical professionals. His wife, Corinna Betsch-Schumacher, a German equestrienne, has already traded their $25-million jet and holiday home in order to support his weekly care.

His neurosurgeon Tony Belli has confirmed that in order to rehabilitate him for his traumatic head injury, he could spend years in hospital. So many people spend even more than three years under treatment. "It depends very much on the severity of the injury, how young or fit they are," he explains.

He began to show some "moments of consciousness and awakening" in April, said Kehm. The news was confirmed by Luca Di Montezemolo, his ex-boss at Formula One.
