1. "Speaking through some masks dispersed largest droplets into a multitude of smaller droplets..smaller particles are airborne longer than large droplets (larger droplets sink faster), a mask might be counterproductive."

2. Coughing is NOT the issue.
Large droplets are NOT the issue. Breathing exhales MUCH MORE virus in fine aerosols than coughing. Finer aerosols bypass masks/nose & reach the lungs. Masks NEBULIZE.

3. Masks increase mortality because breathing through them nebulizes aerosols into smaller ones which bypass mucosal immunity & reach all the way into the alveoli, leading to acute respiratory distress syndrome (ARDS).

Masks nebulize aerosols, finer aerosols:
1 Contain the largest concentrations of virions
2 They persist in the air up to many hours
3 They bypass mucosal immunity and reach deeper into the lungs all the way into the alveoli
4 Collapsed alveoli cause ARDS

Now look at what your nose can do: it's better than a mask on all counts: it filters and provides strong mucosal immunity defenses at the same time: https://twitter.com/robinmonotti/status/1351837060408233985?s=19
