The businessmen of the world who are not taking environmental matters seriously are just wasting money, aside from damaging the environment it's wasting money and in this economic climate you just can't afford to do that.

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 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.

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

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.
