A week ago I was in a crowded room with over 1,000 GA government bureaucrats, mostly healthcare.
We did a stupid HR type exercise where we stood uncomfortably close to another person face to face.
Many of us had a high fever for a couple hours that night. Then it passed and we went to work the next day as normal.
An event of natural immunity. You don’t have to do it. But understand what happens when a crowd gives out a minor inconvenience to prevent a major event later.
That sounds more like psychosomatic than actually getting exposed to anything. Almost nothing out there is going to give you a fever hours later, incubation periods are 2 to 3 days. That whole thing sounds like a BS exercise to get people back in the silly “tough it out” mentality.
