This concept i offer is so stupid, childish and impossible that it becomes laughable. So i put in the comedy section
The great mafia that would cull the human population and leave alive only docile,Harmless machine-like servants.
What would interfere with their plans are intelligent critical thinkers, alpha males and natural born fighters.
They must know exactly who these people are the sooner the better
If they have a database of non comformists and troublemakers they can send their contact tracer agents to test them posative and infected with "CV19"......arrest them and put them into special detention centres never to be seen again.
In australia its already happening
Crowds of demonstrators could be singled out using agents with concealed sensative breath analizers inserted into
Their coats/bags/jackets. As soon as their earphones regester the unique (possibly DNA carrying) breath, they move to another victim nearby
Heres part of a paper i found.....
We're all unique snowflakes, as evidenced by our fingerprints. But our prints and DNA are not the only features individualized to each of us. New research shows that our breath, too, can be used as an unique identifying feature, thanks to the varying assemblies of internal microbes that inhabit our bodies.
To discover these unique “breathprints,” ScienceNOW reports, scientists recruited volunteers to blow into a mass spectrometer, a machine often used in chemistry to separate chemical components of different samples. Within seconds, the mass spectrometer spit out results for each person. These breathprints not only vary between individuals, the researchers found, but also change throughout the day within individuals in reflection of shifting chemical reactions within the body. But a unique core signature always underlies a person’s breath, to the point that it could be used to identify the individual participants in the study.
In the future, breathprints could become the new urine tests, the researchers think. Breathprints couple be a more surefire way to tease out drugs a person may be taking, or to find out whether an athlete is doping, bringing a new meaning to the term “bad breath.
