Why do we laugh? Neuroscientist Scott Weems will tell you in this informative book describing the neuroscience behind laughter. His theories are insightful (despite being a bit stereotyped) and peppered with humour! However, I have to agree with him when he indulges in some self depreciating humour quoting Avner Ziv, “It is more enjoyable to read a humorous book than to read one explaining humor.”
