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

I was very, very lucky because I started swimming when most of the landmarks in the world had not been swum.

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.

If you've got a problem and you multiply it by 50-million people, it becomes unsolvable, but if you've got a problem and you divide it by 50-million people, it becomes solvable.

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

I was asked to give a speech on the Everest swim, and during the Everest swim, I changed. I changed as a person, I honestly did. That mountain changed me, and I gave a speech about it for nine minutes.

We have to appreciate that we are part of nature, we must work with nature; the environment is our lifeline.
