Yep... but Like I said... either the "science" has changed in a couple months' time, so the recommendation was changed... or it was a very public Lie being told at the highest levels in March/April to limit the public wearing / hoarding / purchasing of masks...
Which is why I take all these "recommendations" and "science based projections" with Caution in practice... but also with a grain of salt... knowing they can be completely wrong, off my a mile, or changed tomorrow...
Science (by definition) is the ongoing/relentless questioning, observation, and testing in the search of truth/knowledge... and to say were are there in the latter part of that definition - is a stretch at best... and dangerously arrogant at worst. JMO.
