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.

When it comes to my racing career I'm very driven and very selfish. People who are around me at races will know that I'm a different person here than in my personal life. I completely blank people at races. I need to be focused. I'm rude.

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 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.

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.

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

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.
