We simply don't understand the human body well enough to know why some things work and why others don't.
Correct, but after this the correctness of your comment ends.
The human psyche plays a significant role that pure science doesn't admit to because it can't be proven in a test scenario.
It's called the "placebo effect" and pure science has shown it many, many times, in many, many test scenarios.
We know the human body gives off energy but people refuse to accept the "auras" are possible or significant for some reason.
Define "energy". Heat? Or something else? Show some kind of evidence backed by data rather than groundless assertions of the significance of auras.
We know every brain has a distinct pattern with a general consistency to that pattern, but we refuse to believe it's anything more than electrical.
What do you propose it is then?
