My 'Movember' moustache was never going to be as big as Nigel Mansell's, but I tried my best. The amazing thing is that when you try to grow a moustache, you notice everyone else's. There are some amazing moustaches on the grid.

When you're in a car which can win every race, or fight for a win every race, that is pressure.

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.

If I ever have a son, and if he wants to follow in my footsteps in Formula 1, my main responsibility will be to point out some of the negatives.

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.

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.

In the car and in front of the camera I tend to be very calm but behind the scenes I can get fired up and passionate, I just don't see the need to shout my mouth off in public.
