Mount Everest is a very spiritual place, it's a beautiful mountain.

I've seen some glaciers in the world which have been, which are just turquoise blue blue glaciers up in the Arctic. It's tragic to think that because of climate change, because of man's actions, they're melting away.

I got bored and then joined the British SAS. It was five very exciting years of my life, and then I'd always had this passion for swimming, so started swimming around the world, in some of the most exotic and distant and dangerous locations.

I'm one of the lucky people that, my job is my passion, is my hobby. I hope this doesn't sound arrogant: I truly feel that this is what I'm meant to do, to swim and to talk about protecting the environment, my two passions.

You shouldn't be able to do a swim at the North Pole, it should be frozen over.

Sometimes we set boundaries for ourselves in life, or even worse, we allow others to do so. In many cases, these boundaries are just in our mind and need to be pushed away.

Ordinary won't change the world.
