This is actually two things. #1. A wonderful video on science and false or inflated claims, and #2. A fabulous demonstration of why you should question everything from the person who identifies him/herself as an authority based on credentials, to the recommendations you read in the media.

In other words, believe what you find, don’t find what you believe.
