defecation less future?
Yes. Unfortunately I couldn't find it in the english Golden Age, but there is an article in the German version of it, in the February 1924 issue.
It is a "question from readers" asking whether there will still be defecation in paradise, or if the electric ring will stop it. The answer says that defecation is a side effect of sin and imperfection. In paradise, perfect bodies will be able to utilize perfect food perfectly, so there will be no excrements anymore.
