Fascinating. There are ways to control your brainwaves with biofeedback. I was extremely good at that many years ago, so good I was part of a network tv show.
So, perhaps I know how to stay alive.
My parents were into that crap.
Had a device you put on your head like a sweatband with wires and a little transistor radio sized box with a speaker and oscillator in it that you were supposed to change the frequency of with your mind.
They were also into that Bio-rhythm garbage, Dale Carnegie, Self hypnosis, Napoleon Hill, Astrology, all the 60’s & 70’s rip off scams..................
