Maybe worried is too strong a word. Concerned is more appropriate. I figure when its my time, not much I can do about it. But I see no reason to be stupid about it and engage unnecessary risk. Ya know, like licking doorknobs, hugging politicians, and so on. Doesn't stop me from doing what needs done around here and never has. Its the feckless cavalierity that is the problem. And if you purport "masks are for sissies", that's exactly the attitude I'm referring to. Put on a damned mask and go about your life responsibly. Stop shutting down society and get on with it responsibly. Those that won't should be publicly humiliated for their selfishness. Give science a chance to catch up with this, instead of passing the cooties around. That's all. Is that too much to ask of supposedly smart people?
