Cyanide

Holy Moley, talk about long posts. And I thought I was text-based bag of wind.

I don't think I am going to even begin to throw my hat in on this one.

Wash hands
Bleach door handles
Mask coughers
Cough into sleeve
Gargle with tap water if someone coughs/sneezes near you
Don't put dirty hands on face

That will keep you from getting sick
