Can I assume that we underestimate the power of things that aren’t a physical enemy (or something we can’t physically see)? Like the corona virus. Explain why.

Yes it is some, mostly or generally we human's under estimate every hing.

We thing ourself that we are the owner or the biggest of all than other organisms or creatures well it's not the matter.

We must never think ourself great even a small any can do much harder things which we can't do.

Similarly the novel corona virus is very very small microorganisms it harms us but we must not under estimate it's power of things of anything/anyone.
