He has no actual clue, thats for sure. On top of all correct items you mention, some stuff is completely benign and should be left alone. Nobody will know that until operation or other, very invasive procedures are taken which have their own risks anf consequences. Especially at older age, many things killing slowly are just too slow and other items will surpass them in achieving that kill, ie prostate cancer in basically all men (according to a close friend who is swiss urology surgeon its only question of time we all males get it, but most of the time you dont know about it and it progresses super slowly). There are many things like this. That doesnt mean there isnt a room for improvement. I have some bad experiences too, but my wife is a doctor and medicine is HARD, every case properly unique. IT and stuff google et al do is trivial and deterministic by comparison. We all would like this idea that medicine can cure it all, but we are far, far from it. But some folks apparently just love reading "10 things THEY don't want you to know about XYZ" articles and actually believe them.
