So many people remember his video and the story. When talking about mental health he shouldn't use those techniques and pray on emotions to get message delivered.

At least, when he said child was diagnosed with bipolar disorder he should add some joke, like Britney Spears too or he should use some scientific fact. Also, focusing on one disorder only, charming people, talked just right amount of time to persuade people ... Anyway, he did wonderful job. Video is great. Read is on the spot#1 byw
