Keet van Zyl is on crutches, with two screws in a broken ankle and a plaster cast up to his knee. He has had to swap a 4x4 pick-up for his mother's automatic so that he can keep driving - and for all this trouble he can thank his profession.
Van Zyl, 30, is an accountant and a trailblazer in the profession's most far-fetched branch: "extreme accounting". The South African gets his thrills from skimming across rivers and down mountains while wearing a number cruncher's sensible suit and tie with a laptop under his arm. "It combines the adrenaline rush of accounting with the everyday routine of extreme sporting activity," he says on the phone from Cape Town.
