Wonder if certain tones would resonate with certain pains. Several decades ago, at a physics convention, it was reported that coherent radiation was generated from or near the human brain. Couldn't this carry a lot of information. Since the brain sends it out, perhaps it detects this radiation. We eat legumes, we detect olfactory evidence.
Warm air flows at high speeds over the surface of skin.
It seems it would be useful to study these flows on several hundred people to categorize them and see if differences are symptomatic for certain conditions. I am a very healthy person. But if all time and space is connected, the precipitates could be self centered holographs of the whole.
