While we wait for the completion of Today’s paradigm offset, this popped out on google.com. From Physics organization.

The video on this page is an incredible demonstration of how human aerosol presumably carrying the COVID-19 is virtually impossible to stop. There are people out there that claim to be using science in making their decisions going forward, let them see this. Once you see this video demonstration of aerosol you would have to say that this covid has already been passed around more than we realize.

Again from physics org a complete demonstration as to why face shields are in-effective. The clain is that regular masks are more effective than shields, but just watch that video as well. Squirrels turning the cages for today’s offset, standby 1 – Pilot talk 🙂
