Michael Schumacher, with his wife's help, signs a helmet for a charitable cause

Poco se sabe sobre Michael Schumacher desde que sufriera un accidente mientras esquiaba en los Alpes franceses en diciembre de 2013 y que le provocó una grave lesión cerebral. Al heptacampeón mundial de Fórmula Uno no se le ha vuelto a ver en público desde entonces y su situación está rodeada por el secretismo absoluto por parte de sus familiares.

However, his condition has not prevented him from signing a special helmet that British Jackie Stewart, 85, a three-time Formula One champion, will use this Sunday during a tribute lap at the Bahrain Grand Prix to raise funds for dementia research. The three-time world champion founded "Race Against Dementia" after his wife Helen developed the disease.

Schumacher received assistance to inscribe the initials MS on a white helmet that Stewart wore during his career, and a spokesperson for the former German driver's family confirmed to Reuters that these details about the German's signature were accurate.

The Bahrain GP organisers announced that all 20 living Formula One world champions have signed the helmet that Stewart will wear when he drives his Tyrrell, the 1973 title-winning car, on Sunday, marking the 60th anniversary of his Formula One debut.

“It's wonderful that Michael was able to sign the helmet for this noble cause, a disease for which there is no cure,” Stewart told the Daily Mail at the Sakhir circuit. “His wife Corinna helped him and completed the helmet of every champion who is with us,” Jackie added.
