Why don't you send me a link to the actual study? Academic papers are full of things like methodology, citations, and detailed claims that a 6 minute video cannot substitute for. Even the links you provided didn't link to actual studies, but rather exceedingly brief articles on the subject. I'm being serious, if you want me to review evidence, send me real evidence (i.e.: the actual studies), preferably that you have read yourself so that we can discuss it intelligently.
