It is easy to write a book and make lots of claims. I saw people in my own family who believed in "positive thinking" and avoiding "in error thinking" to avoid sickness. They got sick died just the same.
You notice none of those people who promise mind over matter ever start getting younger & younger? I mean, if you can get rid of illness through their methods, why not aging?
I think this forum is for alternative health helps, in this world.
