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.

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.

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.

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.

My school reports always used to point out that my concentration levels were appalling. I never listened in class because I was always daydreaming about racing. I never thought for a moment about doing anything else. There was no guarantee that I'd make a career in it but I never had any plan B.

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.

My father did everything for me. He was awesome.
