Their pigs are running around the streets amongst the sewer and the nastiness and the garbage. It's just not a good deal. Now the Catholic Church, they believed this was God's wrath and that's what most people believed. So they believed if it was God's wrath that you couldn't be sinful, therefore you couldn't be gluttonous, so you shouldn't do things like buy new clothes, change your clothes a lot, or take baths. And scientists at that time period were saying that baths would open your pores, which let the bad air in. So if their solution is no bathing, not changing our clothes, and in fact some people thought that it would be smell that would ward this away. So sometimes they would take feces and rub it over the victims of the plague to try to cure them.
