2007-09-22 explanations?

I was led into buying this as one of the Opies of childlore fame compiled it... Yes. a host of BRITISH superstitions are listed - but simply alphabetised (so there are few 'connections' made), and very few explanations (of any kind) or origins are explored. Some one can guess of course, some are nuts, and some are too famous to bother with, but that leaves hundreds where one is given five occurrences of the belief from 1600 to 1960 - but no clue as to WHY the practice sprung up. Surely that's the interest of superstition... Disappointing.
