Kate Humble began her television career as a researcher for children's programmes such as The Chroma Zone and Parallel 9, before getting her big break as co-presenter on Animal Hospital. This then led on to a stint as a presenter on Top Gear and numerous reports for Holiday.
She used to be a smoker, but gave it up in 2004. When she did smoke, she prefered to hand-roll her own cigarettes.
She's suffered from Malaria twice. When she was 31, she caught the potentially-fatal Cerebral Malaria during a visit to Zanzibar and had to spend a week recovering in hospital. Two years later, she caught it again on a trip to Ghana.
Her father used to work for IBM.
She has a younger brother named Charlie.
Since having had her ears pierced, she's rarely seen without a pair of her favorite medium-sized gold hoop earrings.
She's a fully-qualified and very experienced scuba diver, and her diving skills often feature in her TV roles.
Having finally had her ears pierced in 2008 for her 40th birthday, she celebrated her 41st birthday in 2009 by having her belly-button pierced.
When she appeared as the subject of an episode of the BBC TV series Who Do You Think You Are?, she discovered that, during the Second World War, her paternal grandfather had been a distinguished test pilot, while her maternal grandfather had been involved in the "Great Escape" from Stalag Luft III.
Having become interested in bees following a feature she presented on them in 2004, she became a beekeeper in late 2009, and is a member of the British Beekeepers Association.
In October 2009, she became the President of the Royal Society for the Protection of Birds (RSPB).
After leaving school, she spent some time traveling around Africa. During her trip, she worked a number of jobs, from being a waitress to working on a crocodile farm. She also spent some time working as an assistant in a magic show, where she was the girl who got sawed in half.
When she was 23, she married TV producer Ludo Graham, who she'd first met when she was 16. Having moved from Chiswick in west London in 2007, the couple currently live on a smallholding in the Wye Valley with their two children, Bertie (born 1994) and Lawrence (born 1996), and their dogs, Badger and Bella.
She didn't get her ears pierced until December 2008, when she had them pierced the day after her 40th birthday. She had them done so that she could wear a pair of expensive diamond stud earrings given to her as a birthday gift by a friend who'd forgotten that she didn't have pierced ears.
Her wedding ring, a plain 18-carat gold band, is a family heirloom that originally belonged to her great-grandmother.
Although she was born in London, her family moved to Berkshire when she was just nine months old, and she grew up in an old Victorian farmhouse next to a working farm.
Kate: (When asked if she'd ever consider having plastic surgery) I hate the pressure on women to look a certain way and have tits a certain size. It's madness. Can I just say I'll never wake up and think, 'Sh*t, gravity's taken hold!' I can't imagine it.
Kate: I don't wear lots of jewellery, and never have. For years, all I ever wore was my wedding ring and a watch, and that was it. Now my ears are pierced, I'll usually wear earrings as well, although I do sometimes forget to put them in or think 'to hell with it, I just can't be bothered today!' And I did go a bit crazy on my last birthday and get my belly button pierced, so I've got that too. But that's usually all the jewellery I wear, because I just don't feel comfortable wearing anything more.
Kate: When I was about 19 I thought I wanted to work in TV, so I got a job helping a casting director. One film we did was a drama, Spymaker – The Secret Life Of Ian Fleming. But when it came to casting a girl to play the house mistress' daughter at Eton, the director became really picky. Basically, Ian had been caught in flagrante with this girl, so it was just one scene, but the director wanted to film it 'over the hip' and naked. Eventually after days of castings, my boss asked me to go along to boost numbers. I ended up getting it. Hysterical. Jason Connery ,who played Ian, was delightful, as I confessed I had no idea about acting. And yes the director got his 'over the hip' shot, closed set and everything. Basically, it was a very funny day, never to be repeated.
Kate: I'm not a big drinker. I'm quite square. I hate the feeling of being drunk, so I try to avoid it. It's lovely to have the occasional gin and tonic, and I love sharing a good bottle of wine with Ludo, but I have to get up so early most days I can't drink loads.
Kate: The most unusual job I've ever had? When I was 18, I spent a few months in South Africa working as a magician's assistant. I'd be there all dressed up in the spangly costumes, jumping in and out of various boxes which he then stuck swords through and that sort of thing. And then, at the end of the show, he'd saw me in half. It was hard work, but a lot of fun - Especially being sawed in half. It was always an interesting experience to feel the saw go through me, and then look over and see the box with my bottom half in it fifteen feet away on the other side of the stage!
Kate: I don't really do jealousy. I was brought up to think that if there was something you really wanted, you worked to earn it, and if you weren't prepared to put in the work you didn't really want it.
Kate: It's not fashionable but I like Marmite on apples. A friend of my grandmother's was a vegetarian back in the days when no one was, and it was her favourite snack. She introduced it to me and I became obsessed.
Kate: (On finally having her ears pierced) It does feel a bit strange to have them done after all this time. I forget all about them for ages, and then I see myself in the mirror, see the studs there, and think to myself 'oh yeah, I've got holes in my earlobes now!' But I do like having them done, and I'm looking forward to having loads of fun trying different kinds of earrings to see which I like the best.
Kate: (Speaking about how many people view women on TV) It is irritating that people assume if you haven't got a degree and you don't look like the back end of a bus that you must be daft with it.
Kate: From a celeb perspective I'm quite dull. I live in Wales, I've been married forever, I've got two very normal teenage sons, I have a dog – I'm not going to suddenly start going to parties and shopping in Gucci.
Kate: I'm not an academic or a specialist, but I do love learning new things and asking questions – I'm never afraid to ask.
Kate: (On working with Bill Oddie on Springwatch) I never, ever get bored. Bill ranges from being unpredictable to downright difficult, but he's passionate about his subject and has made an awful lot of other people so, too. You can't knock that. Sometimes I could cheerfully throttle him, and we have some heated (unprintable) exchanges. But the bottom line is I'm terribly fond of the old sod.
Kate: (On finally getting her ears pierced) I'd actually been thinking about getting my ears pierced for a while, but what really decided it for me was when one of my friends forgot I didn't already have them done and gave me a pair of really expensive diamond studs for my 40th birthday. Of course, because they were for pierced ears, there was no way I could wear them so, the very next day, I went out and had them done. I've only had them pierced for a few weeks now, so it still feels a bit strange and I'm still getting used to them, but I like how they look and definitely wish I'd got them pierced ages ago instead of waiting until now.
Kate: (On her enjoyment of public nudity) One of life's great joys is dancing naked in the sun. It makes me feel so good. Even now, there are all sorts of places in the world where you can take your clothes off and not be seen.
Kate: (On her poor school record) I was a very bad student. I had a fantastic Latin teacher which did mean I did Latin A Level but other than that my school career wasn't something to be proud of.
