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.

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.

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 think fans of the sport have a good understanding now of how fit Formula One drivers need to be.

I think social networks are really working for the drivers, because we're able to talk directly to fans and they get first-hand information. And I think it's great for the partners as well and the businesses that are involved in Formula One.

A lot of people think Formula One isn't a sport because everyone drives a car when they go to work in the morning. But we're pulling up to six G on a corner or during breaking, which is almost like being a fighter pilot. So we have to do a lot of work on our neck muscles.
