As you rightly point out, h, I am a words man. I'm awfully good at analysing and decoding language to extract its deeper - often unintended - meanings. For this reason, when I espy words and phrases such as 'non-linearity', 'highly unpredictable', 'could', 'can', 'may' and 'are likely to', I'm forced to conclude that the writer is bullshÃ*tting wildly and has no more clue of the likely outcomes than do I.
