I tried to argue with a couple of Bemus Point business friends about dangers from the corona-19 virus, to no avail.

Knowing that pictures are worth more than words and pictures of 3 d assemblies better yet, below are CT scans, printed in my labs with 3-D printing, from the data of the lungs of a Covid patient.

The comparison is with good lungs. I have several other examples. The source was a patient in a small hospital near Toledo (think The Hospital by Brian Alexander) and the patient had come there from a nearby nursing home. The decay on one lung is almost complete. Recovery from that Covid thing? Probably better not to get it in the first place.

If you haven’t been vaccinated, make work of doing so. 91,000,000 Americans are now in areas where the delta mutation of the virus is growing rapidly.
