What adults certainly miss is childhood credulity and curiosity. One without the other is like putting a bag on a plastic mind, although adults would seem to be in the credulity line.
So...this book contains a few unbelievable "facts", which plausibly gain something by being controvertible. I have already found several contradictions to the idea that Queen Victoria killed her husband (although the fact that he had stomach trouble for years now sounds suspicious), but I will list a few of the more outrageous "facts", which I may or may not have confirmed by the time you've read this, in order to jog your senescence, if you have it.
Unfortunately, as a child or adult, most readers are likely to be bored by 4 pages illustrating the typical day of a maid, etc. Not even sure how exciting the pages about Victorian school life would be for students who mostly still recognize same. For such a short book, for such a astonishingly rich literary era, the excerpts and "facts" seem mostly like desiccated lists and filler for a few Victorian poems and songs referred to as "vile".
-- Education in UK only became free for every child in 1891.

-- "The Great Unwashed" referred to the poor who didn't have enough water to both cook and wash.
