1. Masses were not meant for close quarters.
2. Modern sanitation, in large part, extended the average life expectancy about 30 years since the 1800s (see Here).
3. Hunter gathers lived as long if not longer (See Here.)
4. Bad hygiene is a product of civilization mitigated by a product of civilization (sanitation).
5. Was it really worth it?
