The banana question has puzzled me for a while. I heard on a radio programme many years ago that monkeys in the wild open their bananas from the "other" end, wondered why, tried it myself, found it was easier and have done so ever since. It has puzzled me that so few people do it that way. I can cite Slate in my support, but then again who takes advice from on-line economics columns about how to eat their food?
The bluestocking question was raised in my mind by Loades' biography of Cecil, in which he uses it a couple of times of well-educated Elizabethan women. I found the term somewhat quaint and a little confusing, and wondered whether this was a case where an old-fashioned term is considered offensive by those to whom it would be applied today (as is often the way with old-fashioned terms). The answer in this case seems to be a general but not unanimous "yes".
Thanks for the input, everyone!
