Roman Plumbing: Overrated

One thing that really is mind-bending about the ancient Romans is their total lack of privacy. You went to toilet in public, with friends. You went to the toilet in your home as your slaves prepared food around you. You had sex with a slave standing over you in case you got thirsty and needed to send for water. Being alone for any reason was a totally foreign concept. Slaves talk. Anything you did was public knowledge in fairly short order. For this reason, Romans also really didn't have the concept of the self-defined man. For example, donating anonymously to feel good about yourself was simply not done. Who you were was what people thought of you.
It's hard to imagine the larger Roman cities, and Rome itself, could exist without some manner of legal and technological organization to manage sanitation.
Standardized earthen plumbing pipes with broad flanges making use of asphalt for preventing leakages appeared in the urban settlements of the Indus Valley Civilization by 2700 B.C.[5]

Researchers have found that open defecation leads to stunted growth, and also higher child mortality rates. The later could explain another puzzle of India--why Hindu children have higher mortality rates than Muslim children, even though Hindus are on average richer and more educated.
It turns out that Indian Muslims are about 20 percent more likely to use toilets than Indian Hindus, regardless of income level.
