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

What I'm asking people to do is to look at their lives, wherever they may be. I mean, you may be a housewife or a mother in Gauteng and you're driving your kid to school, you know, and you've got one kid in the back and you're driving 30 kilometres to school and 30 kilometres back, so 60 kilometres in a day, to take one child to school. Is there a possibility that you can put a few more kids, some friends' kids in the car, and start saving on those types of things?

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 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.

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.

Very few things which are really worth achieving come easily. Sometimes they do, but most of the time you really have to work hard and cleverly.

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.
