SCIENCE - What is so great about science?
Science is like that NAIL you pounded into the wall a while back because you needed a place to HANG YOUR HAT.

Imagine you’re moving into a new place. You thought you saw a closet by the front door but were so excited to sign the lease you didn't notice.
NP. You get your toolbox & grab a hammer & nail. You pound a big nail deep into a wall stud &, voila: a place to hang your hat.

All is good, for a while. You later realize there is a better place to hang your hat. You know if you pry out that first nail it will leave a big hole & you’ll likely damage the wall a bit too.
You can just leave it and put a NEW NAIL somewhere else.
So that’s what you do.

Your friends come over and keep hanging their hats on the first nail even when you say, “Hey, there’s a new, better nail over here”. It is obviously a better nail in a better location.
Oh well.
So, what about DISTANCING & CONTACT TRACING?

6 FEET
6 FEET for 15 minutes.
These “hat nails” are kinda silly.
Mr. Know-It-All SCIENCE told us our spit drops to the floor less than 6 feet from our mouth, & the virus in our spit is thus no problem.

We now know that smaller droplets, aka aerosols, can carry virus in air for much greater distances for much longer times.
And as air becomes colder & drier the bigger droplets will partially evaporate, become smaller, and be more likely to hang in the air.
Move the nail.

This fact gains importance as schools open & people move indoors as the cooler, drier air of fall & winter approach.
Plus, anyone who’s been spit upon by an excited or loud talker can tell you it doesn’t take but one second to catch the spray in your face.

OK, so I don’t know exactly what “viral load” it takes to initiate infection with novel coronavirus, ie, how many inhalations of aerosol-laden air it takes.
Maybe our friend SCIENCE has sorted that out, but if I move my nail over there I will prepare to move it again.

What I do know is that if you take comfort in sitting for 14 minutes, 6 feet, 6 inches from a contagious person, you ought to track down a pry bar and move your nail.
Of course that’s just my opinion, I could be wrong.
