Is There a Toilet in the Street?

If you imagine who had the worst diarean all throughout human history, where would you look? At what point time would that have occurred? It's got to be a like peasants, basically, right? My mind goes to mediaeval times, sort of generally. But like, it's just got to be peasants from every era,. Because they don't get processed foods. And when everything was run by horses, you know, like they really wait for a toilet. They just in the street. Not only was sewer in the street, but also the roads were powered by horse poop.
