WHY VIRUSES?

Someone exhales and emits an invisible cloud of virus particles. A person standing by inhales those particles and two weeks later they are in the ICU, medically comatose, breathing with the aid of a ventilator, struggling to stay alive. What the hell!

What are viruses for and why do they keep using people to replicate, while also sickening and even killing the human host? And despite our super-scientific efforts to destroy them, they keep mutating to more resilient, resistant, and even deadly forms.

Enough is enough already.
