So they're dumping their waste, their human waste into the streets. They're bringing animals with them as they flee the rural areas because of the drought and the famines that are going on into the city. They're bringing their pigs. 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.
