For the next lull in a conversation, here's everything you'll ever need to bore everyone about the history, euphemisms, and etymology of excrement disposal. For everyone on earth, regardless of wealth, poop is the great equalizer. In a deeply divided world, it is one of the things that connects all humans. All food, whether it's a bowl of Fruit Loops or a steak and lobster dinner, ultimately results in the over 20 billion pounds of poop that we collectively expel worldwide each year. Toilets and toilet paper are an essential part of modern civilization, yet few people take the time to consider the fascinating journey they have undergone to reach their current form. From basic systems in ancient times to the advanced sanitary systems we have today, the evolution of toilets showcases humanity's ingenuity, societal changes, and an increasing concern for hygiene and public health.
