It doesn't matter how much money you've got, or how many connections, there's always something you want that's out of reach.

I've spent as much as 30 grand on a watch but it's not about flaunting my wealth. I don't have many extravagances but watches are my biggest one. I must have 30 of them now. I've been collecting since the age of nine, when I won a black TAG in a karting event.

I think social networks are really working for the drivers, because we're able to talk directly to fans and they get first-hand information. And I think it's great for the partners as well and the businesses that are involved in Formula One.

I love cycling, running and swimming. In recent years I've competed regularly in triathlons, which means I don't find the physical side of driving a struggle any more.

When I'm on my own, I can be negative. I need my friends and family around to help pick me up if I've had a bad qualifying session. I think insecurity plagues a lot of sportspeople.

If I run I lose so much weight, which I need because you're limited on weight when you are a tall driver. And have you seen marathon runners? They're quite skinny.

I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.
