Mike, one of the names for this is The Tea Test, after the biologist Sir Ronald Fisher ran an experiment to test whether his colleague's claim was true. Dr Muriel Bristol-Roach maintained that she could tell whether, on tasting a cup of tea, the milk had been added before the tea or after. Lots about this online, of course. I can probably help Stephen Scharf with the mysteries of canine (and feline) intuition... your dog or cat is waiting for you when you get home because you locked the house when you left. Oh, and they really do have a sense of time, within the day, partly due to hunger cycles. Also they hear your car from 200 metres away, your handbrake in the drive and finally - the real clincher - your key in the door. Smart, right? No reductionist science involved.

Jack may be the catalyst to your success, Mike. Nothing spurs me on more than somebody saying "you can't do that!". Have fun anyway.
