It's surprising that the "C19" virus only started out about 4 years ago. I thought about it because today, I lost a mask. Yes, I still wear them. Oddly, not because of concern for viruses or germs, but because I tend to have allergies. I tried going without a mask, and I found that I encountered a clear difference when I was on the street without one and so I decided to keep on wearing them.
Anyway, as I was saying, this got me thinking about how short a time it has actually been since this all started. It feel like I have always worn a mask. Most people in this city do not wear them. I think that they were only mandatory for about a year or two. I have not bought masks often. I quickly accumulated a bunch (10?) and I haven't thought about them since. I wash them in small batches, and keep on using them. I expect to stop using them eventually, but I'm in no hurry.
