So someone today said I should watch Deadwood, which I noted had Calamity Jane in it. She worked in Dora DuFran’s famous brothel that coined the term “cathouse”. From there I noticed that Dora was in wikis categories of both American Brothel Owners and American Prostitutes, which is a subcat of Prostitutes by Nationality, which is part of Sex workers by nationality, which is part of People associated with the sex industry by nationality, which is part of People by occupation and nationality. Or if you prefer being international you can get from “people associated with the sex industry by nationality” to People associated with the sex industry, then either Sex industry or just the awesome People by Occupation which finally leads to the top level People (which can then go to “Humans” or “Society” and perhaps one day “Society” will go to “Dolphins” and “Dolphin People” or something).
Just the level of detail you can drill down too in wiki sometimes scares me.
