Hi Friends,

I have a special guest today! Brian Johnson is a family friend who is an HVAC Engineer and Aerosol Expert. We discuss air particles and what that has to do with covid and masks. You may want to watch the video instead of listening because he shows some great visuals that are very helpful in understanding all the science. 

As always, I end with a short History lesson. 

Thanks again for listening!

God Bless!
