When I was a child, Lego came in brick form, you'd buy boxes of random bricks. You used your imagination and your mind in your build.

The jungle is my least favourite environment. It's always damp, and everything tries to bite you, whether it's flora or fauna. But I think it's important to face your fears and not just go for the comfortable option.
When suddenly your focus changes, you see the years going by and it's an extra reminder that you don't want to live life with any regrets.
It's not a surprise that the mental health epidemic is affecting so many people because we can't escape this bubble from being on our phones and tablets.
I'm a naturally upbeat person. Friends sometimes compare me to a labrador puppy, and I take that as a great compliment. I love life, I love people and I've got loads of energy right up to the moment when I'm suddenly asleep.
Lego for many parents is the antithesis of the high tech world. We are desperate to wean our little ones away from the tablets and into the bricks.
As our focus turns to the oceans and the seemingly impossible task of repairing our marine habitat, we could look at Everest as a fine example of turning back the clock.
You learn so much about how far you can push yourself and what you can do. How an experience like Antarctica helps you, it boosts your confidence.
On the face of it there is a pristine white sandy beach, but within an hour, around 100 of us can collect up to 250-300 kilos of rubbish. It's mostly bits of plastic, fishing line, nylon, bottle caps. We've found everything.
Geography was the lesson I always looked forward to most. It was a form of escapism. It could be bleak midwinter outside but inside you're learning about African farming methods or the Great Lakes. No other lesson had that excitement.
Many locals in east Africa are calling for fences to separate wildlife and people. They argue it will reduce conflict and also make it easier to protect the wildlife from poachers. From my experience in Tanzania, no fence and no militia will hold back the tide of poachers drawn by the huge sums of money at stake.
Hopepunk is a spirit or a mood. It isn't an actual thing. It is a feeling. It is the Scandinavian concept of 'hygge' or 'coziness' of the mind. It is a warm, happy, charming, uplifting concept that leaves you with a fuzzy feeling in your tummy.
I am very proud of rowing the Atlantic Ocean.
I'm the son of a vet and grew up with golden retrievers. Dogs have always loomed large in our lives but labradors have the nicest personalities: kind, loyal and caring.
Part of the beauty of wilderness schooling is that the overheads are very low. You want a classroom? Build a shelter from nature's store. You want to eat? Forage for it.
I'm a bit dyslexic so I found learning to read hard. I muddled up the letters but learnt to power through.
I remembered reading about a disease called Leishmaniasis, which matched my symptoms. I'd always thought it was an old wives' tale - a sand fly bite that eats your flesh. But when I looked on the internet and saw pictures of people who had it, their lesions looked like mine.
Some people confuse confidence with arrogance. There's no doubt in the business world there are a few big egos and I think arrogance can get in the way. But if you have the confidence to go to your higher superior and say this is wrong, it can make a difference.
I do try to reduce my carbon footprint a little bit by travelling around London on my electric bike. A lot of people raise their eyebrows but I love riding it.
In some ways, I'm in danger of doing too many things to be able to appreciate and enjoy them. I look forward to thinking back to carrying the Olympic torch, or going to the Royal Wedding, when I'm in the middle of the ocean on my own far from anywhere - that's when I'll relive those moments.
Often, a seemingly clear clean beach has a huge amount of hidden litter.
I don't want my children to feel the same sense of failure I did growing up because they're not good at passing tests.
I love the ocean. Anywhere near the ocean will do. Preferably the Atlantic Ocean.
We experienced a miscarriage at 13 weeks and then a few years later we lost our son Willem at 30 weeks. I held him in my arms and had to organise his funeral.
Let's be honest, some people are better suited to exams than others in the same way that some of us are more sporty or arty.
After all, island living is where I began on Taransay, and I have such fond memories of it.
I am honoured to be taking part in the Diamond Jubilee flotilla along the Thames in my 20-foot rowing boat. The energy levels will be high, partly because I'm planning to ply the crew with thermos flasks filled with Typhoo!
I loathed my first term boarding at Bryanston school in Dorset. I hated being away from home; I think I had my parents in tears every time I spoke to them. I regret being so spoilt because within two terms I loved it.
There is something very appealing about moving to a faraway place.
London really is my city; I was born within a breath of Marble Arch.
People are being overwhelmed with social issues, political problems and economic problems - and this notion of giving everything up and going to live off-grid and to have a simpler way of life is quite attractive.
I've had enough of the bleak headlines and divisive politics, dark TV dramas and hate-filled social media. I'm embracing a new movement with a slightly ridiculous name and a single mission, to make the world a better place. It's called 'hopepunk'.
I think we are becoming more obsessed about getting a certain amount of likes on our Twitter and Instagram accounts rather than actually living a proper, real, honest and organic life.
I'm acutely aware of the environment but I'm far from perfect - I love Land Rovers and fly too much.
I can't even cook an egg. The only thing I can do well is baking bread. I love it and find it incredibly therapeutic.
We tend to default to complacency. Stick to the easy option. We all do it. We've tried to create a business model and society around us that is as easy and boxed as possible. We love creating boundaries and borders.
When I reached the summit of Everest, I scooped some ice into my drinking bottle as I'd run out of water and hoped it would melt. After I got back to base camp, I decided to keep it, so I had a special bottle made with an inscription - it's my lucky water.
I really, really loved Fair Isle. I'd always wanted to go there. It's so beautiful and a very small but very international community. Every nationality that you can imagine have settled there.
In many people's minds, Everest has lost her crown. She has become a mountain synonymous with death, exploitation and pollution.
Where once Lego offered a whimsical form of escapism into the world of the subconscious, encouraging creativity and imagination, it's transformed into a rigid 'box ticking' discipline where children are encouraged to build by conformity.
We so love to stereotype people in this country - I can relate to that myself as I've experienced it. By taking on challenges over the years, I've tried to show people I'm not just some 'posh boy' and that there's far more to me.
I wouldn't want to go into mainstream, Downing Street politics, though - it's just too cut-throat. I've got quite thin skin.
I don't enjoy doing exercise at the time, but I enjoy the feeling afterwards.
I'd quite like to run the Great Wall of China. I've never been to China and there's something about the Great Wall of China that is so iconic and evocative. It's only 3,000 miles. It's not that far.
I got rounded up by the police in Quito as I didn't have my passport with me. I was in prison for a night, which was pretty frightening, made more so when one of my male companions started crying.
I take echinacea to ward off colds and I go through phases of taking vitamins, but I'd rather eat a lot of fruit and veg than take pills.
Without risk you can't experience life. There have to be risks, physically and mentally, taken by everyone.
I know some people obsess about their appearance but I don't - it's not something that bothers me.
Holidays are our one big family indulgence.
I'm not one to complain about illness. I suppose I have a bit of a stiff upper lip. I just tend to get on with things.
