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.

We all drive differently and have different styles. For me I need a car I can develop beneath me and feel comfortable in. If the car feels neutral and unbalanced it doesn't work for me.

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.

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

My time at Honda was amazing. Some of my best times in Formula One, actually. I might not have won races, just one race, but I had a lot of fun.

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.

It is such a special feeling to win a grand prix.
