These health issues should not be taken lightly for they may portend wider use of arcane and secret methods to disable targeted persons.
Electromagnetic radiation, poisons to food, water, waste and air, acoustic signals, vibrations of structures, visual stresses, the panoply of human bodily senses, can be weaponized to disorient, wound, cripple and slowly kill over a period of time and in doses that are not easily tracked.
Advanced nations have been experimenting with these little known weapons for decades which parallel and overlap research into attacks and defenses of communications.
Biological warfare, chemical warfare, acoustic warfare and other scientific explorations into combat have been publicized to some extent but much of it remains classified, and somewhat prohibited by international treaties which never keep up with advances carried out beneath the gaze of designated observers of treaty compliance.
One need only to note the vast releases by Edward Snowden of highly secret intelligence tools to grasp what is likely occurring with other technologies, some tools gross others extremely subtle, quite a few capable of hiding among unsuspicious haystacks.
And never forget medical and disease experiments on Blacks and prisoners in this century, nor more immediately, the official early dismissal of the threat of Covid-19. Even now the flat-earth faithful vehemently object to the threat of Covid-19 and challenge its natural weaponization against puny political hokum.
