As much as this video may have been filled interesting information Dr Berg, was trying to sell products. I watched the video and then took his quiz. You must give an email address and he wants a cell phone number, which I refused to give adding only 0's. When done with the quiz questions I was sent this note:

I then printed out my long result and was told which of his products would work for me. Please do not waste your time or money on this advertising. It is a sneaky way of offering something for free to get you to buy his products.
