I do agree. It's a decision I have to make when going to work; hence, why I think it's important to test for COVID. Like it or not, many of us have no choice but to go to work if we've got the sniffles and symptoms of a cold. People have been going to work for EONS with cold symptoms. The common cold is contagious, but it's actually not that contagious and hand hygiene and control symptoms goes a long way to not spreading it. It doesn't spread like COVID. So, if I've got a cold, and I truly know it's just a cold, I will go into the office because I have to walk that line of job performance. If I know I've got COVID, I won't go into the office period because I know how transmissable it is.
But anyway, I was agreeing with you that it's not the reality for most people that they can hunker down indoors for any and every illness. In a perfect world? Sure.
