I understand that this video is rather long, but you should find that viewing is worth it.
For me the real prize comes at the very end wherein Bruce summarizes how the bio physical links to an external higher spiritual dimension (and Bruce Lipton states that he had traditionally been a non-believer of such notion of God or a higher external power, but his study inexorably led to his revised conclusion).
To facilitate watching/comprehension, recommend downloading it then viewing it in segments as time permits.

If you do not desire to invest the the time for the full lecture, then I recommend listening to just the last 30 minutes.
