My last post was kind of a test to see if you possessed a sense of humour, Shimmers, and I'm pleased to say you have passed...though I still think some degree of data selection is necessary in order to formulate an informed view on anything; one has to evaluate each piece of evidence, weigh all available information up before reaching a considered conclusion.

I'm never wrong, Sue, just that every now and then I'm differently right. Then again there's such a thing as the right kind of wrong, and, conversely, the wrong kind of right. A lot of the contributors here, IMHO, are the wrong kind of right.
