From the rare glimpses that you get of him in the paddock this year, Michael Schumacher doesn't look as if he has ever been away.
You're aware that he's coming long before you see him, because his approach is always heralded by a clutch of photographers, all trying to jog backwards while scrambling to capture a shot without tripping over one another.
When he does appear, the walk is the same - quick, purposeful, and never breaking stride for an instant. He learned long ago that if he falters even for a moment, he'll be swamped.
