Fans of the former Formula One (F1) racing icon Michael Schumacher should never lose hope that his health condition could improve one of these days.

It has been years since Schumacher's tragic ski accident in the French Alps left him with critical head injuries. The seven-time F1 world champion has been in a coma since Dec. 2013 and has been moved to several hospitals until he was allowed to stay at his home in Sept. 2014. His family opted for a media blackout to protect their privacy and since then, not much news and updates were heard about the racing legend and his health condition. Still, fans take whatever news they can get about their F1 idol, and reports about medical professionals continually saying "never lose hope" are certainly good news for them.

"According to a Swedish study, between 30 and 40 percent of patients have regained consciousness within four years," said Professor Mark Oberman from the Centre for Neurology of the Asklepios Clinic. "Many can come back to life and see how their children and grandchildren grow up, what plans they have or what else happens in the family or circle of friends," he went on to say.

It's been four years since the accident, and the findings of the study mentioned by Oberman — which notes people in such situation may regain consciousness by the fourth year — could ring true for Schumacher. But while there are no guarantees, the professor emphasized that the best anyone — especially the racer's family — can do for now is to constantly give him love by remaining in physical contact with him. 

Many are hoping that this fourth year will be the time Schumacher finally wakes up. Although that is what fans had also hoped for in the previous years, it is always good to never lose hope.

Most people would say the racing world needs a legend like him. Germany is slowly but constantly losing interest in go-kart tracks — something that Schumacher had highly encouraged youngsters to attend especially those who wanted to become future racers. More and more go-kart tracks are losing business due to the lack of interest from the public, and someone like Schumacher could do a big positive turn for this.
