The most impacting human “virus”

It may have different strains and it has its own origin.

It changes and can be mutating. There is full evidence of human to human transmission. It affects key cognitive functions with deep impact on lifestyle and relations. It moves from group of people to other groups of people. Even with no direct physical contacts. Just like a virus. But it is faster than any other reported virus ever.

Fortunately, it is a “human friendly” virus.

Its technical name is CULTURE.
