Philippe, a fan from Lyon, waves a flag as he attends a silent 45th birthday tribute to seven-times former Formula One world champion Michael Schumacher with Ferrari fans in front of the CHU hospital emergency unit in Grenoble, French Alps, where Michael Schumacher is hospitalized January 3, 2014. His agent said on Wednesday that Michael Schumacher was in a stable condition and it was too early to talk about his further prospects. No further update was given on Thursday, the day before his 45th birthday. Schumacher is battling for his life after slamming his head against a rock while skiing off-piste in the French resort of Meribel on Sunday.
