He has a gf, Carine, here is a pic of her in Marseille in 2007:
His hobbies: VIDEO GAMES!
Games in general, I guess, I know he played chess too, don't know if he still does.
He's quite versatile, was talented for a lot of things before he decided to play tennis.
He used to play the piano, but he doesn't anymore afaik.
He was very good at golf too.
A smart guy, interested in a lot of things according to the articles about him. He was a good student, tried to study economics by correspondence, but gave up after a while.
He's a real chatterbox. Quite lazy too.
