Loving note and warning

Renée sent over this beautiful and very heartbreaking picture she received today from her grandchild in the Bay Area.

Kids are scared and worried right now, like most of us. We all need to be loved and reassured.

On the topic of the coronavirus, an MIT researcher says that the six foot distancing Covid-19 rule is based on faulty hundred year old modeling. She says it should instead be twenty seven feet.
In the JAMA article, Bourouiba wrote that peak exhalation speeds can reach up to 33 to 100 feet per second, thus creating a cloud that can span approximately 23 to 27 feet.
Here is the scientific paper, Turbulent gas clouds and respiratory pathogen emissions.
