I always wondered what it was like for scientists trying to pull the curtain down to expose AIDS or that tobacco causes cancer.

No one’s going to test before your holiday gathering.
Not for Covid.
Not for Flu.
Not for RSV.
But you could. You could show them how it’s done.

🙋♂️ Just curious… At what point are academics going to start masking/demanding air purifiers?
How do you reconcile your job as one that teaches students to think while simultaneously causing permanent damage to brains and inability to think?
60% of transmission is pre/asymptomatic.
ITS AIRBORNE!

What’s up BlueSkyers?
Like this if you still care about your brain and avoiding early onset disease from a disabling airborne pathogen…
In other words, like this if you are still wearing a mask every day.

How to erase a pandemic:
Step 1 — tell the Left the vaccine ends it.
Step 2 — tell the Right the vaccine IS it.
Step 3 — sit back and relax while they tear each

Masking makes sense. SARS-CoV-2 can persist, and new evidence from France shows infected megakaryocytes + platelets — meaning real blood involvement. This virus isn’t just respiratory, and protecting your air protects your blood.
Don’t know anything about viral persistence? Know that it’s the norm👇

For me, choosing to wear a respirator mask in all public spaces signifies an awareness of my connection to the human community, whose collective well-being is grievously threatened by the ongoing pandemic of Covid-19.

I hope you will read along with me… the writing of someone who doesn’t self-promote, who has insights that cut through like a knife to truth.
Thank you for the kind words, Sean. Unfortunately, in four decades of writing I failed to get a book of my own published, but many pieces of my writing, both fiction and nonfiction, are available here:

We all get fooled sometimes. It's life. Character is built on what you do when you find out about it. Do you deny it and continue the lie or do you grow as a human and just admit you got fooled.

Is there a book like White Fragility…
but about American adults and the air they breathe?
Because someone needs to write the book on why a nation that buys air fryers, air fresheners, air purifiers, scented candles, and aromatherapy oils…
won’t fight for clean air that keeps their children alive.

Learning loss didn’t come from “lockdowns” or remote instruction.
It COMES FROM (still happening) illness.
Illness caused by COVID.
Illness that makes kids miss school and teachers miss teaching.
SICK DAYS. And the vascular damage that causes incapacity to think & retain.
This is still happening.

Every time Covid and learning loss hits the news, people act like the only factor is folk staying home and learning online, rather than… Living through a global mass death event.
