When I'm filming survival requires movement. You need your energy and you've got to eat the bad stuff and survival food is rarely pretty but you kind of do it. I get in that zone and I eat the nasty stuff but I'm not like that when I'm back home.
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.
