David Coulthard to Retire

At 37 years old, Scot David Coulthard is the "grand old man" of formula one racing. But it's been revealed that he is set to retire at the conclusion of the 2008 season.  This from Coulthard:
My decision to retire was taken earlier in the year, and is based on a desire to stop while I am still competitive and enjoying the immense challenge that grand prix driving represents. I also have the desire to look for new challenges within the sport.
The decision to make this announcement at the British Grand Prix should be an obvious one for all to understand, as I have achieved two of my 13 F1 victories at Silverstone and I am a member of the British Racing Drivers' Club, which hosts this event.
It was also recently announced that Coulthard and his wife are expecting their first child.
