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.

I can't eat whatever I want, definitely not. I'm always controlled because I do a lot of fitness and triathlons, not just Formula One, so I always make sure I eat the right things.

I always sleep really well, particularly before a race, when the adrenaline's pumping.

I always think I should try to get to bed early, but then I can't stop myself from watching telly and fiddling around on the net.

My 'Movember' moustache was never going to be as big as Nigel Mansell's, but I tried my best. The amazing thing is that when you try to grow a moustache, you notice everyone else's. There are some amazing moustaches on the grid.

My school reports always used to point out that my concentration levels were appalling. I never listened in class because I was always daydreaming about racing. I never thought for a moment about doing anything else. There was no guarantee that I'd make a career in it but I never had any plan B.

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.
