OTOH it is not much different than going to a movie, a sports event or
a make out bar. It is just more politically charged.

We still haven't seen anyone talking about the bloom of cases from the
BLM riots.
Maybe there is something about being outside or maybe tear gas and the
smoke from burning buildings does kill the corona.


Maybe wearing masks and being outside both make a big difference. I have
read that there were not many indications of mass spreading from the
protests. One person said that they had larger spread for a single bar
than protests at the same time.

The less we breathe each other's exhalations, the better. Outside is
better, in a room well ventilated with fresh air is not too bad.
Recirculated air is worse and worse still is a closed crowded room.

Our second wave is expected to hit as people go indoors more and breathe
in each other's exhalations more as northern Winter approaches. The
problem is we are still on the first wave.

In NY state apparently shopping malls can only open if they have a
special air filtering system installed. That struck me as bizarre.
These malls have huge air spaces, even stores like Macy's the ceilings
are very high, lots of open space compared to the number of people
in them. So why there and not businesses, regular stores, supermarkets,
apartment buildings, etc? Most of those have more people in less
air space.

It would be interesting to read about how they came to that decision. I'm
sure gfretwell sees $$$ as a major factor - he might not be wrong if he does
think that.

Must meet MERV-3 apparently.

MERV3 is barely adequate to catch saw dust, basically that woven
fiberglass filter people used to use in their furnace. (20% of 10
micron particles)

What do you figure the MERV number is for all of those T shirt rags,
bandannas and neck gaiters the sanctimonious are wearing?

I notice the idea that health care workers can just wrap an old T
shirt around their face went away pretty fast.
As Chevy Chase said "but it is good enough for you tho".
