I've got two dogs - one's a Jack Russell and she's one year old now, and I've got another dog called Kanga, and I got him from a rescue shelter, and there's nothing I enjoy more than just walking them on the beach in Cape Town. I find that very destressing and very relaxing.

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.

Ordinary won't change the world.

I think every child in every country, not just South Africa, every year should go to a national park, and it should be part of their basic curriculum.

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.

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