Prince of Space in comment #1,207 said he wrote a book on it. Any idea of the title, or if there is a book or news article where he spells it out?
You must mean comment 1,205. I remember reading about it, but can’t tell you from originally where. This newer article from 2020 explains it pretty well. It’s a Daily Mail UK article - US MSM would never print anything like it because it’s not good for Joe.

Also in the article it says he is writing a book but he is holding the title pretty close to his chest.
