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.

I think as a 20-year-old you expect life to always be easy. You get given a good hand and the chance to race in Formula One. You think the driver can make the difference, can make up for everything else within the team. But that is not the case. You are racing in such a competitive sport so that doesn't happen.

It doesn't matter how much money you've got, or how many connections, there's always something you want that's out of reach.

You look back and you remember the good, the bad and the ugly

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.

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.

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.
