This video is one of a series. Once you watch it, I recommend going to their site, bookmarking their site, watching more of their videos, and checking out their store and the various other tabs on their sites. This site has very interesting specialists and scientists and a lot of thought-provoking information.
You can view the video here. However, again, since it is one part of series I recommend finding the rest of the series or purchasing it from their store.
