I guess when you're on 'Blue Peter' there's that goody-two-shoes image which people find attractive.

My parents are proof that arranged marriages can work. It is a great part of my culture but I grew up in a completely different place, so I wouldn't want anyone to arrange a marriage for me.

The internet creates a mask and you are talking to people who you don't necessarily know.

When they do actually get pregnant, most expectant mothers understandably keep the whole thing a secret because of how fragile the first four months can be.

A problem shared is a problem halved, but as with so many problems affecting women - periods, menopause, post-natal depression - we often feel embarrassed, as if we're moaning or just plain wrong to air them.

I did this show for Sky called 'King of the Nerds', which was a reality show looking for the world's biggest nerd, essentially, celebrating the geek, which is also what I'm about.

We rip out a perfectly good kitchen worth thousands of pounds, only to replace it with another costing roughly the same. The old one has to be disposed of, the new one had to be made. From raw materials, factory processes and transportation the extra effort is substantial. Overcomplication.

I don't really worry about things, I'm too busy.

My dad moved to Britain from Bangladesh in the 1960s to work as an actuary for Prudential. However, after seeing an empty retail space in Soho, he decided to open an Asian restaurant instead, despite not having any business experience.

A Final Say referendum on the Brexit that actually lies in front of us will give everyone a tangible and decisive vote. I and most people, Brexiteers and Remainers alike, want the same thing - the best for the UK.

I think relaxation is escaping from your everyday encounters. You can read the words on a page and be transported to somewhere else. And the more consumed you are with it, the more you're cocooned.

Never mess with other people's kids. You will never win. It's the child's word against yours and they have parental reinforcements as back-up. You just can't triumph.

Journalists know other journalists - that's the only reason my engagement made it into the papers. I don't think real people are interested - just the media, just Twitter!

By fermenting tiny single-cell organisms we will be able to synthesise all manner of foodstuffs in the future, everything from pasta to eggs, fish and meat. Small tweaks in the process will enable production of different proteins used to replicate food we already eat.

No one went to the ballot box to vote for something worse than the status quo.

If, as statistics suggest, millennials' diets are more plant-based than ever, and we continue to bring up our kids to eat less or no meat, the future could be bright - the future could be vegan.

I have thick hair which is like Plasticine - it's mouldable. So I'll fashion it into some creation that looks presentable. I often wear it down because I have a tiny head and small face, and my hair adds volume to help disguise my pinhead.

Getting the spot of 'Blue Peter' changed the path of my life.

I'm lucky in that the media is much more freelancey. So I didn't have that pressure that lots of people have if you jump off the ladder, then you get left behind.

Ethnic minority women generally have poorer outcomes from their pregnancy compared to white women.

In all aspects of our society we overcomplicate things under the guise of making things easier and simpler, when in fact we are doing the opposite.

When I was growing up, I always felt a bit like I didn't quite fit in, a feeling that perhaps still lingers in the background to this very day. I was the small brown girl in the big white suburb.

When I was in the sixth form I presented a cable and satellite programme about music, television and video. I used to do public speaking competitions.

I do sometimes like cheesy music like 'Africa' by Toto; naff songs and music.

The one thing more important to my parents than my career is that I am happily married.

I remember being in Vietnam in my early 20s, at the height of Lonely Planet's fame, and all the travellers would converge on internet cafes to send emails back home. It was a great place to exchange tips and recommendations, so you actually interacted with people.

I grew up as a Muslim: it was quite a conservative upbringing; I didn't wear mini-skirts. But my mum and dad had a good sense of humour and were creative. I guess all of that shaped me.

My first ever interview for 'Blue Peter' was a film with JK Rowling.

I say throwaway, jokey things. When you're young-looking and you are presenting something that has gravitas you can't look down your nose, but when David Dimbleby does it, it's OK.

In general, I think we're more or less shaped and formed by our late 20s. Things come along during that time that make us cynical. By the time you're in your 30s, it's hard to unpick those mindsets that have formed. It takes years of therapy to undo them.

I had an instamatic wind-on camera and remember buying the flashcubes and fixing on top of the frame. The flash credits were limited so you had to be careful not to waste any.

We as parents, and the control culture, it is our responsibility to make sure we give the right perceived norms and the right cultural conditions.

Me and my husband think the internet is a really positive thing. We know games that have taught our children problem-solving skills but that doesn't mean we are going to say play 'Call of Duty.'

From a young age I was really into pop music because I had these two older sisters who were into it, and I wanted to be like them. They liked Wham! and so I was really into them too.

I'm the youngest of three children and grew up in Ealing, west London. My eldest sister, Nutun, is nine years older than me, and my middle sister, Rupa, is three years older.

My mum is your archetypal Asian mum, always feeding people. If there was no food in the cupboard, she'd still manage to rustle up a feast - Bangladeshi food such as pilau rice, curry and korma.

Food lovers tend to make life difficult for themselves on their travels. It's like travelling first class, if your expectations are so high, you're bound to be disappointed.

You're an example as a kids' presenter, so there is a responsibility there. But they got lucky with me - I'm not into heavy nights out.

I'm really not aware of much press. I could drive myself mental if I went on the internet. I'd probably overanalyse it anyway. There's so much media that I'd feel bombarded, so I don't pay it much attention.

My A-levels were physics, chemistry and maths. Science is fascinating but I wouldn't say I have used it since then. I decided to do economics.

Economics is a good degree to have but the subject is very theoretical at Cambridge and I found it frustrating that you can't apply a lot of the models to particular circumstances.

My husband Charlie says I get ready five minutes before I go out the door. I am one of those people who can't do anything unless it's imminent - that's how I roll.

I have surreal dreams, so much so that I can never make head nor tail of them.

I don't usually eulogise about people, but I saw Russell Brand doing stand-up before he was really high profile. I didn't really know what to expect but I laughed until my belly ached.

Because my parents are Muslim, there's no doubt they wished I would marry someone Muslim.

My parents really wanted me to have an arranged marriage when I was younger, but I think they have updated a bit with the times.

I've worn a chainmail suit to swim with sharks, glided over Cirencester with a James Bond-style paramotor strapped to my back, eaten hippo steaks and had a bat dive down my bra. And all the while, I had to face the camera and smile.

Life in 'Blue Peter's' world is always presented as happy, positive and fun. It's an adventure that you have to make the kids believe they want to join in. There are no marks for being a scaredy-cat.

The brilliant thing about 'Blue Peter' is the variety of the stuff you do and the experiences that you have, just amazing experiences.

Because Blue Peter can get you access to places - if you go to somewhere like Nasa, you don't just see what most people see, you can get a lot of behind the scenes access. You can talk to an astronaut.
