Why Did Ancient Humans Drink Dirty Water?

Ancient humans had no microscopes, no germ theory, no idea what a virus even was yet they survived drinking water we'd call poison today. Here's the real, science-backed story of how. In this video, we go past the basic answer and dig into the actual history: Egypt's 3,500-year-old water filters, the Indus Valley's forgotten indoor plumbing, parasites still found inside 5,000-year-old mummies the beer-vs-water myth historians still argue about, and what modern gut microbiome science says about our ancestors' immune systems. Plus the 1854 London cholera outbreak that finally cracked the mystery everyone had missed for thousands of years.
