We go to the banya, the Russian spa. And you go into the sauna, which is really hot, much hotter than a normal sauna, and then they beat you with branches.

It's always flattering when you get compliments, but it's more of a measure of who you are at the time than anything else.

Digital exclusion is a difficult issue for families across the whole of the U.K., including my own. I love seeing my nan, but with such a busy schedule and a long distance between us, I don't get to see her nearly as often as I would like.

I use a stylist, which wasn't something I imagined I'd ever do, because I like shopping, but because we prerecord 'Countdown,' I don't want to wear something that everyone has from the high street by the time the programme goes out.

If I find a dress I really like and it happens to be a bit short, I'm not going to lose any sleep over it. The thing about going to Oxford is it does give you the confidence to be how you want to be.

In TV, you get so many different opportunities, and especially, you get to try something different you don't get to do as a normal person, then great.

People can underestimate you when you're blonde and from Essex, but it's easy to shut that down. I used to get dumb blonde jokes when I was 18, but when I replied that I was studying maths at Oxford, it usually shut them up.

From my personal experience, because I'm in a relationship, on paper I would never have imagined - I'm an Essex girl, maths geek who likes football, and I've ended up with a Russian ballroom dancer, and I guess the things you think are important, especially when you're younger, turn out not to be.

When I see myself on screen, I don't even feel like it's me - it's like it's a completely different person.

You sit men and women down and give them a maths test, and they will do fairly equally. Then you set up the same test, but with different people, and make them tick a box to say whether they are a man or a woman, and the women do significantly worse in the maths test than they did previously in a group set.
