Break60, this article was posted here at HW/PC 2-weeks ago, and there was good discussion in that thread.
Rather than re-hash, I suggest that if you wish to add something to the conversation, go to that link at post a comment.
Here's the link:
www.healingwell.com/community/default.aspx?f=35&m=3615687(I would also comment to you that your own posts will draw quite a bit more interest if you add a valuable observation or comment about
an article's link, rather than just post a link and expect others to go read it.)
