In this film about dopamine, we learn how too much mediates an addictive personality and not enough causes parkinson's disease.
It's a really interesting idea I think, but the way it's presented, perhaps a little drab. No offence to the presenter, but I think he has quite a boring voice.
I think the video could be made more entertaining by giving a kind of personality to dopamine.
