Great Question! This is what I wanted to know. What about spreading germs with our hands. Germs on door handles into stores.
Nothing about Covid seemed like a plague to me.
I guess I watched too many westerns.

Germs are not bad things.
Assisting in building immunity, substances put on hands to kill germs, many are toxic and doing harm.
certain pathogens and substances to be avoided.
In nature people are best communicating with many organisms.
No need to rub hands on dead animals, and waste.
Those covid shots, best not touching these people or being around them in close quarters, best not touching what they are touching.
People have been taught wrong and trained stupid.
