Transferring Knowledge

Have you ever thought why humans are so great compare to the rest of living things? I think it's the ability to transfer knowledge consciously from generation to generation to come. Animals are doing it by genetics, which takes a very very long time. And speaking is all about transfer knowledge.

His TED talk is interesting because he focuses on the hormones in our brain to understand what happens when stories are told. Dopamin, Oxytocin, Endorfin - Angel's cocktail. Cortisol, Adrenalin - Devil's cocktail. 

As a speaker, it is helpful to understand this emotional change of the audience consciously. And also, it is important not to manipulative about it. You need to feel the emotion you want to deliver to your audience. Otherwise, it looks phoney sometime. It's a human communication. You need to be trustworthy to be heard as a speaker.
