I felt confident at 24, but I am a better driver now.
My father did everything for me. He was awesome.
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.
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.
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.
I always sleep really well, particularly before a race, when the adrenaline's pumping.
For me, triathlons were something that was down to me and my fitness. Now, I really enjoy the pain in the triathlon of chasing someone down. It's a bit like chasing down Nico Rosberg in the last few laps at Silverstone - it makes you feel alive.
You're pulling 4-5G for a lot of the corners around the lap. We build up lactic acid because there are a lot of vibrations in the car, and you have to have strong legs to hit the brake pedal. We need to be fit to do every lap at 100%.
