There's a noticeable push to urge the use of N95 masks. I've been reading about them a bit.
For reference, the COVID virus is said to be 125 nanometers across. The shortest wavelengths of visible light (violet) are roughly 400 nanometers.
Promotions for N95 masks tend to point out that COVID viruses travel in aerosol droplets, and therefore will be filtered out well with N95 masks.
The problem is that water evaporates. [It also erodes the electrostatic properties of the N95 masks that makes charged particles stick to the fibers. EDIT: My scientific opinion, which may be wrong. My sources say the electrostatic effect is diminished by filling up with particles or by being coated with microgoop.]
Additionally, broken-up COVID viruses become nanoparticles--particles of size smaller than 50 nanometers, which are just about the size that N95 masks filter worst (at 95% efficiency, at best).
Sometimes I wonder how we're not all dead yet.
A boomer apologizes, albeit without much clarity.
"It is not meet to take the children's bread, and to cast it to dogs," Jesus said; Matthew 15:26.
I recently understood that I am spending my life in rebuilding spiritual and practical foundations that had been foolishly undermined by previous generations.
Several months ago I was reading a nonfiction book by Christian author Paul Tournier, and made it about three-quarters of the way through before being drawn away to other things.
When I picked it up this last week and finished reading it, I found references to about a dozen Bible passages that had come up in my daily Bible readings in the interim, mostly obscure Old Testament personages with a variety of afflictions; Tournier was a Swiss doctor famous for connecting his Christianity with his medical practice.
I also read a Christian fiction book this last week: Deadline, by Randy Alcorn. One day, what I read in the book mirrored my morning Bible reading on that same day.
"A work of creation was three-fold, an earthly trinity to match the heavenly; the Creative Idea, timeless and passionate, which is the image of the Father; the Creative Energy, begotten of the idea and working in time, which is the image of the Word; the Creative Power, the meaning of the work and its response in the individual soul, which is the image of the indwelling Spirit."
-- P. D. James, summarizing Dorothy L. Sayers' description
