World Expert.

If you Google "Hugh Culverhouse cyclist," the second item on the search is a reference to one, "TrikinDave." I discovered this some time ago and it came as a bit of a surprise that I seem to be an authority on one-legged cyclists.

I’ve come across a couple of curious cases of unexpected expertise. My brother-in-law once made enquiries about an important but esoteric piece of information relating to his work; having made a chain of phone calls to various experts around the world some-one, who obviously hadn’t picked up either his name or his place of work, told him confidently that, "the person you need to talk to is Mr. So-and-so of Such-and-such company"; it was, of course, B-i-L. He had once been asked the question at a conference and started his answer with the words, "At a rough guess . . . ."

Again, a bee-keeping acquaintance in more modern times wanted to find out about a similarly esoteric aspect of bees’ wax usage though his search was more successful. Having emailed various experts around the world he was directed to the man to whom he really needed to talk; so, after phoning up the gentleman in question, he walked around to see him.

Edit. I've just looked at Lady Findhorn's blip for Monday of the Terracotta Palace in India, Googled the building to find out more about it and found myself back at LF's journal; it's now Thursday,
