I wonder how much of this is just that our tests are getting more sensitive.

Exactly, the detection itself doesn't mean anything. Is the dose relevant? If not, then not. And the dose likely isn't relevant.

Agreed. When you zoom in, even the normal life stuff can give you concern. I showed my kids what creatures live on their and others' bodies. You have millions of microscopic arachnids called Demodex mites living in your hair follicles and sebaceous glands, particularly on your face. My wife gave me an evil look as I showed my children this fact in online vids and pics. Granted these are symbiotic/parasitic relationships of life, but still, the closer you look, the more you see!

You can say what you like about the dose being pharmacologically ineffective but I want my sharks completely sober.
