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.

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 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.

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.

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

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