I know this site is selling a e-book but there is alot of good information here that some might want to look at. Most of the links on the left of the page have real studies associated with them and can provide alternate paths for some or all of us to use perhaps. I found alot of it very interesting and like I said the links and info have real studies from reputable sites attached to it. If you scroll down and on the left there are many links with info you might be interested in reading.
I dont plan on buying the ebook but once again found the consolidation of information great to read.
