Many wish to know "what Covid is/was". While there is no single answer to a wide variety of different dis-ease conditions, as some had a "positive test" but never got sick in any way, some had a mild cold/flu for a day or two, and yet others suffered tremendous loss of vitality for weeks/months and even years on end. The following paragraph, written in 1890, describes the moderate to extreme "cases of Covid", including death, that occurred. For those willing to entertain a new idea, here it is:
"Place yourself in a house where there has recently been a panic or scare, though you may know nothing of it. You were well and strong the day before. You arise in the morning, and soon this whole train of disagreeable sensations affects you, because the house or place is saturated with a thought current of fear. Put a fear on a city, town or country of some deadly epidemic or some great calamity, and hundreds of the more sensitive who may have no fear of that epidemic or calamity are still affected by it disagreeably. That thought current affects them in their particular weak spot. A fanatic predicts some great catastrophe. The sensational newspapers take up the topic, ventilate it, affect to ridicule, but still write about it. This sets more minds to thinking and more people to talking. The more talk the more of this injurious force is generated. As a result thousands of people are affected by it unpleasantly, some in one way, some in another, because the whole force of that volume of fear is let loose upon them. Some are killed outright. Entirely unaware of the cause, they open their minds more and more to it, dwell on it in secret, put out no resisting thought until at last the spirit, unable longer to carry such a load, snaps the link which connects it with the body."
There is even more to "Covid" then this in my opinion, which is even harder to believe so I won't delve into this area. Needless to say, since so few are yet willing to contemplate such a possibility, the cabal is almost certainly preparing another such scamdemic in the future. Caveat emptor my fellow anons. Discard all fear!
The loss of smell/taste was a collective thoughtstream but it was indeed brought on by two potential factors IMHO. Shorter-term, the purpose of so-called "Covid" symtpoms for some was to enable the individual to rest, hence the energy and vitality drain. Considering the hardest work your body does every day is to digest food, stifling the taste/smell would induce one to eat far less than normal. Such was the short-term effects lasting roughly the duration of the ailment.
Longer-term, many were affected by the cranial-scrape "nasal swab" procedure which was the height of insanity and absurdity to require such an invasive and painful procedure (humiliation ritual). This undoubtedly disturbs the olfactory cranial nerve which can sustain long-term damage as you suggest. Some even suffered damage to their trigeminal cranial nerve which does explain some of the instances of Bell's Palsy and trigeminal neuralgia - sometimes solely blamed on the jab but many such instances were undoubtedly brought on by the invasive cranial scrape.
I speculate on both of the above and can prove neither point with absolute certainty. However, I know with complete certainty that viruses do not exist and no material substance identified has yet to emerge as even being a candidate for the cause of "Covid" as such a substance would have had to have been a poisoning event.
I also know with certainty that dis-eases are borne of the mind - all of them, bar none. Matter follows mind. A radical position I realize, that few are yet ready to entertain.
In fairness, poisoning, physical injury and severe malnutrition are all causes of physical ailments, but these are not "dis-eases" as Covid clearly was and as dis-eases are classically defined - i.e. cancers, heart dis-ease, diabetes, colds/flus, and on and on - all have their root cause in a conflicting life situation that the individual is unsettled by which is followed by temporary tissue adjustment performed by the subconscious mind until such time as the conflict is resolved/released, at which time, the subconscious mind reverses the temporary tissue adjustment and this is usually the period of the entire dis-ease process in which we "feel sick" - after the conflict is resolved.
