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.

Resting for me is fitness training.

I have made lots of mistakes in terms of contracts and spending money when I shouldn't have spent money.

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.

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.

I keep my weight low, although you need to be able to move your weight around the race car to change the balance. I'm 6ft and I'm 70kg so I haven't much fat on me.
