People have been getting sick literally since the dawn of man. I knew many co-workers who'd come in with a cold or a fever and get the rest of the office sick. Now, there's a virus that's so dangerous you need a test to know if you're even sick with it but people are demanding everyone stays home so nobody catches it. If you don't want to catch it, stay home, but don't ask myself or others to change their behavior
Ah yes, that thing adults routinely do.
