Ben Fogle needs a big challenge to keep him "sane".
The 43-year-old 'Animal Park' presenter - who first shot to fame after an appearance on 'Castaway' in 2000 alongside his pet dog - has travelled the world making documentaries showing him surviving the wild and exploring nature, including shows such as 'Prince William's Africa' and 'Secret Life of Crocodiles'.
Fogle insists he needs adventure to keep him excited about life.
Speaking to BANG Showbiz, he said: "I always need a big physical challenge every few years. As I get older it helps to keep me fit and healthy - and sane. I did a series a few years ago called the 'Secret Life of Crocodiles' where I went scuba diving with wild Nile crocodiles without any protection, no cages, no chainmail. It was pretty terrifying. They've actually banned it now because the presenter that did it after me lost his arm."
Now currently working on a sixth series of 'New Lives of the Wild', which will be aired at the end of this year, Fogle has revealed that he has another 'big' project which he will be announcing later this year.
Despite several near fatal incidents, the thrill seeker is not letting the risk to his health hold him back as he is currently juggling filming of his new series, working on his new book about 'all things English' and work for his new campaign, Act Against Lungworm - whilst teasing at yet more big projects to come next year.
Fogle - who has son Ludovic and daughter Iona with his wife Marina -also revealed he would like to work with fellow globetrotter Joanna Lumley, 70, on a show.
He said: "I love working with different people. I'd love to do something with Joanna Lumley. I've always loved her travel logs, I've met her a handful of times and I think there could be something fascinating with the bringing together of our two different perspectives."
Fogle is supporting the #ActAgainstLungworm campaign to raise awareness of the threat of lungworm to UK dogs. For more info follow @DangerousSnail25 on Instagram or speak to your vet.
