Thanks Tricia,
 it's good to have native speakers check the language. Your edits sound fine with me!

Let's ponder "the Root of Health" (which was introduced by Dr Kwesi as what we are looking for - not as the "magic bullet" but as an understanding and practice). Although it may be jargon, we're there to introduce a new concept anyway, and therefore need to capture attention and whirl the brain around a bit. That's what is the job of the presenter, to bridge ways of speaking, take by the hand on the new path of thiking, and to create the Wow in their audience!

If Presenters can't identify with some wording, or it doesn't seem to be fitting their audience, it's fine to change some words as long as keeping to the contents that we (need to) agree about.  

Regarding photos used, we are happy to have alternatives that are equally free for commercial use. Besides the MHI-owned graphics, there could be a collection of pictures that provide the "right feeling"...
