Yep. Every time someone tells you to "trust the science", tell them to "read their history". Science is the process of determining what is false, not revealing truth like some type of holy writ.

Goes to show you how many doctors, nurses, etc are. Some of the biggest egos you will ever run into in life.

People forget that germ theory only gained prominence at the end of the 19th century. Before that people couldn't comprehend how something so tiny that it's invisible to the naked eye could kill you. Doctors were insulted by the idea that they could spread disease. Even when Semmelweis had data showing lower death rates, he was resisted and was driven out of the profession.

In terrain theory would this matter?

You know who is big on washing your hands?

Matthew 15:1-3 [1]Then came to Jesus scribes and Pharisees, which were of Jerusalem, saying, [2]Why do thy disciples transgress the tradition of the elders? for they wash not their hands when they eat bread. [3]But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?

..... Matthew 15:20 [20]These are the things which defile a man: but to eat with unwashen hands defileth not a man.

Germ theory is a Jewish deception, they love to make you wash your hands constantly.
