Fifty years ago, when I was a child, I got the flu. I remember to this day how bad I felt. That flu was a hundred times greater than any flu I had since. My current doctor insists that I get a flu shot each year. Men at work say I'm stupid and that it's a conspiracy. I believe you build up an immunity.
I believe that the over all cost of Covid should be considered. Who is qualified to set the priorities as we have seen politics enter the arena I don't know.
Drug abuse overdoses, divorces, murders, alcoholism, depression, etc need to be considered as the ramifications of a full shut down. European countries have done the complete shut down, and the Covid cases are returning. What I interpret locally in the USA populous are saying that life should go back to 75 to 80% normal. Take the safeguards of social distancing, wearing a mask, wash your hands, don't touch your face, etc.
I'm not sold on what a mask can do. However, What I will commit to is that any time you wear any personal protective equipment (PPP) your awareness is heightened as to danger existing. So, overall, I think wearing a mask and having to remember to wear a mask is good.
