LOL! Well as long as it wasn't "aneurism", "anabolism" (or indeed even "anorakism" ... inventions are always good !) and there's nothing life-threatening involved ........[grin]

Anahata - in terms of context I don't think you can be said to be an anachronism.... Chambers' definition
= "anything out of keeping with chronology" ... did you intend time to have anything to do with it? or did you mean an "aberration"? (Aren't there some wonderful words in the English language?)

As to the list of things to do - I've either been involved or been to nearly everything on the list locally (except 10 - unless you count watching/listening to stuff) ... although Maypole dancing has not featured on my activities list since I was knee high to a grasshopper, and music sessions don't really feature except sitting around the outskirts at one .... unless you count the use of a deadly (and embarassing) shakey egg???
