Speed and danger the hallmarks of German superstar's lifestyle - on and off the track

Formula One legend Michael Schumacher may have retired in 2012 after a glittering career, but his love for speed and danger has now led to a serious head injury while skiing in France.

The 44-year-old German suffered a blow to the head after hitting a rock at the upmarket Alps resort of Meribel, and although initial reports suggested his injuries were not life-threatening, he was later listed as being in critical condition by the hospital treating him in Grenoble.
