The challenge is those who rush to masks as “a solution” miss the latent real variable that matters, which is you don’t need a mask if you don’t touch your face without washing your hands first + don’t touch other people + regularly wash your hands. 

The reason why this is important is because you might think you’re okay with a mask, except you fidget with it = in which case it was all for naught. 

Or you take you mask off at home, forget to wash your hands and again = all for naught. 

And that for some, a mask might help w/ not touching you face – whereas for others it might cause them to fidget or introduce stress-related anxiety at seeing everyone in masks – that’s better scientific advice based on the data today.
