MKULTRA and all US-based human experimentation and study projects done both on their own citizen and foreigners from other (complicit) countries are quite a trip to read through. One would assume the government pouring so much money and man-effort into these researches would make ruthless individuals feel more justified in committing their overlooked, state-mandated crimes. Of course, being a sensitive, secretive and very speculative subject it's important not to take everything at face value, as there's an abundance of theories and the emotional impact can make one overlook logic. There's really a lot of interesting ones. Familiar with a certain Kaczynski?

The linked article seems to want us to believe that concern about global warming is part of a CIA mind control plot. I would skip it.

No doubt considerable effort has been spent muddying waters, and it's not an easy topic to research, but it might be better to take a look at John Marks' seminal work based on documents obtained under FOIA, The Search for the Manchurian Candidate - The CIA and Mind Control, available for free at https://www.druglibrary.org/schaffer/lsd/marks.htm

I was sick with covid for around five days 2 months ago. I had high fever, tiredness, pain on my body and coughing.

After I felt better I observed that I was feeling much more tired than I usually felt.

Now, after two months I feel a little better but not that much... Could this be related to my covid infection? Is there a way to improve my situation?

I did a normal check up but didn't get anything abnormal...
