Let’s review the official mask recommendations to date in order 
1. Don’t wear masks. They don’t work.
2. Psych! You must wear a mask for two weeks to slow the spread.
3. Actually, flattening the curve is going to take much longer. Wear masks until the curve is flattened.
4. The curve was a myth. We’ll need to mask up until mass vaccinations 
5. Well... there are a lot of unknowns about mutations and the vaccines etc. You’ll need to keep masking. End date TBD
6. Wear two masks. One ain't enough. Infinite masks for infinite protection 
Conclusion. I don't wear masks at all. If that scares you stick with Twitter to talk to me. I'll get beers face to face with real men.
