I love Dr. Berg’s videos. Not only have I learned a lot from what he decided to put up, all on his own; but, I have seen proof that he will make videos based on questions that are asked in the comments (if enough people are asking, anyway).
Also, he just comes off as very charming and real, and nerdly. But, mostly, it’s that he is helpful and seems to really care about others and want to help those who are unhappy or suffering. He’s not all puffed up on his own ego, like some. Just a genuine nice guy, with brains.
