This is a supercomputer simulation done by a science lab in Japan.
If you cough without covering your mouth, this would happen so people around you.

Gross droplets facial

First simulation is without a divider and second simulation is with a divider.
Either way people in front of you will get the nasty facial.

3rd simulation is with a taller divider which is little better but still nasty stuff will spread all around you.

4th simulation is crowded rush hour train situation. Train is running with windows open but if there are so many people inside the car, the air flow gets limited and it doesn't circulate enough so that everyone will breath nasty stuff... ugh.

This visualization is gross with out without coronavirus...

I used to commute like this everyday.

I don't miss this... but I guess people love trains and commute like this.

State of emergency has been lifted in Japan and all these people are still commuting even after corona. It blows my mind that many people don't mind going through disgusting particles everyday... 🤢

What I would like to see is outdoor situation like protesting and shouting at each other and stuff.
I am pretty sure that coronavirus will spread in the enclosed spaces but I would like to know more about what is going happen in the open spaces...
