Pushing the limits

I suppose this is a book review (tl;dr: do not read. However, google for "exosomes", they are interesting suff):

"The Truth About Contagion: Exploring Theories of How Disease Spreads" - Cowan, Thomas; Fallon Morell, Sally (2021)

You know you're pushing the limits of sanity when stuff you read offers a totally novel perspective, yet totally wrong.

My take is that the author(s) identified and expounded upon the problems with Koch's postulates (for establishing causal relationship for pathological agents and disease), and then basically hallucinated an even worse theory of disease using EM waves and food/water toxins (this theory of course fits even worse with Koch's postulates).

There's an interesting mention about "exosomes", apparently it's a packet of stuff that gets produced by eukaryotic cells. According to an (abtract of an) article in Nature it could perform intracellular DNA/RNA transfer: https://www.nature.com/articles/ncb1596 . Now this stuff is interesting.

Given the exosome lateral DNA transfer mechanism, it's very weird that the author of the book had to rely on homeopathic telepathic DNA transfer to get his point across. He claims that electromagnetic resonance instead of physical contact transfers herpes viral DNA...  and he relied on it just to show how "viruses" (which he claims are misidentified exosomes) would give communities of organisms an evolutionary advantage by lateral transfer of defense mechanisms against external stresses... I can't say for sure this is false (the telepathic DNA thing is apparently from a Nobel prize winner...), but the equivalently useful and less unproven claim would be that exosomes perform lateral transfer using the usual methods of physical contact and achieving the same evolutionary function.

You know how much a book is worth when the reader has more clarity than the author on a subject that the reader has just learnt...

Still, the highlight on the problems with Koch's postulates do indicate that modern germ theory might not be as solid as you'd have been taught in school -- maybe still 99+% solid, but caveat emptor. Especially with viruses, the alleged pathogen is basically an attack from the "information" vector. We software engineers know how hard it is to actually understand what the attack actually is. The mystic in me thinks that there can still be "bad spirits" in information packets that we aren't mentally capable of understanding.
