Okay, this question risks sounding immature, but bare with me. I feel like we can address this topic in a serious and historical manner. This is a matter of important historical debate and we need to get to the bottom of this (no pun intended)

Before modern sewage systems were created, how bad was the smell in large urban areas? Lets specifically say in London, in the late Georgian era after massive urbanization began, but before any kind of complex system to deal with the refuse. Was everyone basically just taking a dump in a bucket then throwing it in the street? Wouldn't it just pile up in the streets? Were there people who's specific job was to take the poo away? Were certain neighbourhoods more well-known for the prevalence of feces than others? And what about the average people - "the great unwashwed" - if we met them today would we just think they smelled awful?
