Medical Procedures
In today’s day and age, everything in a hospital is sanitized; back in these days, though, that was definitely not the case. Scalpels and surgical instruments were re-used all the time and were cleaned simply by soaking them in, yes, you guessed it, urine.

In most average homes there wasn’t usually anywhere to wash your hands before or after eating, especially not with soap. This means people were eating with already-dirty hands and also not cleansing afterward. Talk about germs.
