Well that's nice to know that you think they don't work.
I've had my share of other modalities that didn't seem to work for me, but they obviously helped out some people, I keep an open mind and try to figure out what is going on as opposed to saying that it flatly doesn't work.
But when you experience that they do work and your health improves dramatically as a result then I'm sure you would have a different opinion. But that goes without saying.
Imagine if a person tried to blow their nose, but they blew too hard and hurt themselves, or they weren't able to clear their nasal passage. So to them blowing their nose didn't work. And they would state...It doesn't work or you'll hurt yourself.
I find it interesting the people who 'believe' they know what works and doesn't work for other people.
