MR VISSER
Chairperson, I don't have this love which you might think, to work, but may I just ask one question, with your leave?
	Doctor, you just said a moment ago on a question that was asked of you that Chetty had a body to measure and Naidoo had bones to measure, and he worked according to a formula.  If you had the two, a choice of the two, which one would you accept on the probabilities, as being more accurate?
