    Interesting article.. I never heard about:

    "The 6-foot rule dates back to the late 1800s, when a
    German scientist found that pathogens were present in large
    droplets expelled from the nose and mouth."

    "However, wind and weather can affect how droplets travel.
    If the humidity is low, bigger droplets can shrink and stay
    in the air longer. "

    This was amusing..

    "This whole idea that there's this 6-foot perimeter, and if
    you're one inch beyond it then you're safe, really doesn't
    make much sense," said Capecelatro."

    I had people think exactly that if they were just 6ft + inch
    then they were good to go.

    WRT to poor ventalation..

    "If you're in a room and someone coughs, sneezes, or
    speaks, the droplets they expel can hang around for a long
    time," said Capecelatro. "It doesn't matter where you are
    in the room. You are going to be breathing in some of those
    droplets, especially if there's poor ventilation."

    Never thought that clustering would be an issue wrt to
    turbulent...

    "Airflow patterns matter and sometimes can make things
    worse." ... "What the airflow can do, especially if it's
    turbulent, is cause these [virus] particles to cluster, and
    that will increase the number of particles that you could
    breathe in," said Capecelatro.

    But out of common sense, in my shop I have a ceiling fan that I
    engage + I make sure the furnace intake is on most of the time.

    NYU, when they opened back up post pandemic, introduced 15 minute passing periods. They wanted any airborne aerosol droplets to settle before cleaning and introducing a new class of students.
