Its 'remarkable' how little research bacteria gets in public presentation when ALL the major diseases for thousands of recorded years were bacterial plagues. And the fact is that most diseases were eradicated at the turn of the 20th century thanks to hygiene protocols BUT reemerged upon the advent of antibiotics and other medicinal to "treat" infections -- which led to what we immediately ignored with CoHoax --> superbugs aka antibiotic resistance bacteria aka mutations.

And yes we know bacteria exists in our bodies and in most of natural habitats as collaborators -- and when you get sick -- these bacteria that help might die off and you get sicker OR they become more prevalent and get assigned as cause -- staph is a huge example of this. It is a natural bacteria that helps us, but when sick, it becomes an infectious agent and gets blamed -- and then we take antibiotics and create even worse imbalance -- rinse repeat.

And bacteria makes sense -- the mechanisms make sense -- and more so WE CAN SEE THEM make sense -- as opposed to viruses which are so abstract in behavior that some people suggest they are alien bcz they make no natural sense -- and we never get to see them -- even the Wikipedia page for "virus" is just illustrations.

As a mechanical person -- viruses are not in the realm of functional reality.

You mention parasites and ayh wish ayh have done more study on parasites bcz many people point to those as cause of things -- but ayh tend to focus on toxins aka foreign minerals or proteins as cause for so much -- bcz its inarguable that we poison ourselves every moment of every day.

Do you know how one could use terrain theory to cure allergies?
