I do have spare time and I love to read, and I love just to go to a national park and just relax and just think. But most of the time, it's swimming or talking.

Britain has bred many great explorers, but they seem to get so little coverage compared to soccer and rugby players.

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.

Ordinary won't change the world.

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

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

I had a dream , okay, go do a swim off Antarctica, and I'd train in Gauteng and just dive into the sea off Antarctica... You've really got to do a simulated test as best you can in South Africa before you go off.
