The only time I think about life beyond F1 is when I contemplate becoming a dad. But there's no way that's going to happen while I'm still racing. To be successful in F1 you need to be very selfish in lots of ways and you're away from home for long periods. That's not the kind of father I want to be.

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.

The fast, flowing parts, the high-speed corners, that's where a Formula One car is at its best - changes of direction, pulling high g-forces left and right.

To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 320km/h, the noise and the vibrations are incredible. The G-force when you take big corners is like someone trying to rip your head off. You hit the brakes, and it feels as if the skin is being pulled off your body.

I think as a 20-year-old you expect life to always be easy. You get given a good hand and the chance to race in Formula One. You think the driver can make the difference, can make up for everything else within the team. But that is not the case. You are racing in such a competitive sport so that doesn't happen.

If I ever have a son, and if he wants to follow in my footsteps in Formula 1, my main responsibility will be to point out some of the negatives.

I like old tunes when I'm driving. They're fun and uplifting. Billy Ocean, that kind of thing.
