Edit: Romero estimates roughly 70-90% of copies were pirated, which would be actually insane given the popularity of the time

As a desert based society, some of the stuff it tells you not to eat indeed is probably a good idea. Circumcision also serves a purpose in such a society.

Like I’d argue those don’t make sense NOW, but back then it was reasonable advice.

Which particular part? I’m interested and somewhat outside of the situation.
