Hot off the presses, a little good news about anosmia, loss of smell. https://archive.is/dqhGD
tldr: While colds, flu, sinusitis can all cause loss of smell due to one mechanism, obstruction and swelling, Covid 19 has another mechanism. It attacks the substrate supporting the olfactory nerves. This can even lead to loss of the peripheral olfactory nerves. The somewhat good news is that they regenerate. The not so good news is that it takes a long, long time. And though it doesn't say so here, possibly in some cases the substrate destruction can't be overcome.
Interesting. What is also very interesting is that Graphene Oxide (GO) toxicity does the same thing with loss of smell. Just a minute amount of GO inhaled through the sinuses will cause a loss of smell. I theorized that "COVID' was really a bio-chemical attack spread predominantly by atmospheric means.
Then, Clif High mentioned in one of his podcasts that samples of freshly fallen snow in western Washington state were analyzed and found to contain Graphene Oxide. I know in my area, the chem spraying is almost exclusively west of the city, which would mean the prevailing winds would carry the chem trails over the city.
