To drive an F1 car you have to be a little mad. On the morning of a race there's a mix of excitement and fear. If it's a wet track, then it's worse as you're not in control most of the time, which is the thing all drivers fear the most.

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

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.

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 do retire, I know for a fact that I'll never be able to replace the incredible feeling I get when I'm driving an F1 car.

I haven't got the yacht any more. The cost of running it was crazy. But it was so much fun while I had it. I don't regret it.

When I was in Japan with my girlfriend Jessica, she would have had acupuncture every day if she could. I can just about stomach going to a chiropractor and I visited a talented one when I was there, but when he tried a needle on me, it was horrible. My muscles tightened and it didn't work at all.
