Yes, my ignorance, dangit. Back in 1970 I built my first transmitter as a kid. It is nice that you have 17 years experience.
Nobody in their right mind would put faith in any book called " The Cure For All Diseases ". This is true especially because such book has been published for quite a while, and yet, we still have diseases.
If you can refer me to where in that book it tells how to cure tuberculosis, I'd be interested.
Or, where in that book it teaches how to cure psoriasis. yada yada. That book cures nothing. How old was the author when they passed ?
I think you can further your education by studying more and keeping an open mind.
If, after reading ALL the material at the website below, if after reading it you have legitimate questions, I'll possibly reply. You can even find a section in the history portion that deals with the voltages and frequency all you zapper folks are delving in. There is no mystery to this. I charge 1500 bucks for a counseling session, that's worth every penny.
The "zappers" feel good, at least, and make you think something must be happening !! There is value in this, if you convince a person to believe something beneficial is happening, then the power of the mind's intent begins to play a role, see tiller.org But there's also the skin effect that needs to be considered, for those of us dealing with hard Science that is reproducible. There are other possible mechanisms at the reticulo-endothelial system, but you'll never get it with these zappers of Beck and like devices.
Nevertheless, I agree with you in part, that simple "zappers" can have limited beneficial effects, in limited circumstances.
