As has been pointed out many times the early calls for no masks were because there was a shortage for first responders. Regardless, if you do something one way and learn a better way, do you change your behavior or just keep doing the same way?
There is a strong consensus in the medical and scientific communities to mask up. There will always be a few kooks go the other way.
Tell me the last time you saw or heard any first responder, especially any medical personnel not masking?
If they said one thing in March, learned they were wrong in March and changed their tune...you should continue to follow the old guidelines? How dumb can you be?
One thing that bares out over the course of the history of developed society is that medical and science communities can be wrong, and are continually disproven.
That's the whole point of science. It continually changes, improves, disproves itself. Some of the biggest most respected names in both science and medicine were once thought to be "kooks"...
Dumb is relative.
Do I always wear a mask? No. Have I shut down entire industries, set the economy back, put millions of people in the poor house because old folks and people with co-morbidities were more overwhelmingly affected by something than most others? No.
Did I close down college campuses and send kids back to their home towns where they would be forced to live in close proximity with their older parents and even grandparents in a lot of cases? No.
Did I shut down gyms and parks where people can go to walk, run, work out, stay healthy, boost their immune system, and increase their ability to fight off things such as viruses? No.
Did I allow 4-5 months of non-stop mass "gatherings" in cities that at times looked like Woodstock because so many people were packed in on top of one another? No.
Did I shut down other areas of medicine for a while which created a backlog of folks who needed help with other health problems? No.
Have I taken national and even global attention away from things that will have and will continue to affect and kill more people than Covid? No.
If all testing is accurate, and every covid case has indeed been covid, then 40 million worldwide as of right now. 1 million deaths give or take.
Heart disease will kill near 18 million people by end of the year. Maybe less than that because inevitably a lot of them will probably have contracted covid and that will be what is listed on the official COD...overweight, bad ticker, probably diabetic...but covid...
18 million annually...but let's stay inside, remain immobile unemployed, order fast food, binge/stress eat because all you see on the news are covid case and death rates...
