He's more regularly seen tackling vertical rock faces and crocodiles in the Amazon but now TV star and adventurer, Bear Grylls, has turned his attention to a rather different subject: marriage.
In his latest column for GQ Magazine, the zany 41-year-old offers his top tips for a long-lasting relationship - including planning dates nights and working on communication.
He also reveals how he went for relationship counselling immediately after getting married to Shara Cannings Knight in 2000, despite many of his friends thinking they were 'nuts'.

Explaining the reason they sought professional guidance, he said: 'We figured that if [marriage] was the most important thing we were ever going to do, we should do everything we could to stop it breaking in the first place.'
The father-of-three said one of the best tips he took away from the support sessions was to plan date nights once a week.
He explains that activities don't have to be 'expensive or fancy', it's more about spending time together and focusing on what attracted you to each other in the first place.
'Togetherness is what it's all about,' he added.
Family man: Bear, pictured with two of his sons, says 'couples often think that the kids should always come first, but smart couples know that the best foundation for the family is their relationship'
Bear says that the next thing couples should do is prioritise their partners 'above everything else' - even the children.
He continued: 'Couples often think that the kids should always come first, but smart couples know that the best foundation for the family is their relationship.

'In protecting that, they can then best love their children.'
Bear and Shara, who split their time between a holiday home in north Wales and London have three young sons between them - Jesse, Marmaduke and Huckleberry.
Lastly in his column, Bear says communication in a relationship is key and it's important to address concerns early on so they don't start to 'fester'.
His marriage counsellor pointed out that the main cause of relationship breakdowns is not infidelity or disagreements but a lack of communication.
Bear says that before tying the knot it's important to be open with each other about various issues that surface over the years, including in-laws, finances, children, schools, and 'sex, of course'.
Apparently at their wedding Bear and Shara asked guests to dish out their best pieces of marriage advice.

The best came from a from a couple who had been married for 50 years, who advised: 'Never stop holding hands.'
Bear added: 'That's what Shara and I have always tried to do, both physically and metaphorically.'
Offering a final pearl of wisdom, the explorer concludes in his column: 'Great marriages rarely just happen.
'And as someone once said to me: If you ever think the grass is greener on the other side of the hill.. . it's time to start watering your own.'
