Yeah I said it was dhit when my ex-wife said she was going to do it, but it definitely did something.
And I am well aware of the placebo effect.
But just because something is not provable or falsifiable under current scientific knowledge, it does not mean it is neccesarily quackery, there's a Venn diagram there where some things may be effective.
Automatically discarding something that even occasionally gets results, because it doesn't fit current "knowledge" is the height of arrogance.
