I have found it very difficult to pin down the originator of many of the ideas I include in this text. I claim no credit for any of them except those prefaced by ‘in my experience’ or some similar phrase. I would like to give proper credit and acknowledgement to all those whose original work I have represented or mis-represented, but despite the apparent power of the internet it is often only possible to locate an anonymous extract or an un-named report. I apologise now to anyone I have omitted to credit fully. I would appreciate being told of the original reference in every case – if you have it, please email me.

‘The reasonable man adapts himself to the world, the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.’  George Bernard Shaw.
I therefore hope to be unreasonable and Shavian!
