There was an incident at the airport, in the mail room, that fits that description. Then there was the incident at PRIMUS later on today. Both groups affected became ill, and some went to the hospital. (All treated and released, I believe.) Neither incident has been explained.
I don't think there is any way to know, since we are not being told, even if the PTB have the information. I have no idea what happened. I just wondered "aloud" about how I was feeling, and said I had no way of knowing if it was connected or not, and I got smacked around. I still don't know why I felt so lousy earlier, but I feel better now. I didn't draw any conclusions -- just wondered. Heaven forbid one should interject a sentence or two concerning one's humanity. 'Scuse me! /sarcasm (not directed toward you, pnz1!) *G*
