This book was very different from what I expected, which was an exploration of happiness and humor. The author is a neurologist who explored both positive and negative aspects of laughter specifically. I learned a lot and found the book to be very interesting. The most important thing that I learned is that laughter and other emotions are echoed by those around us and we have a greater influence on others than we realize.
The author explains that laughter, humor, and especially tickling are topics that have a very small set of research studies and that it is difficult to get funding for such studies. However, in the author's opinion these topics enlighten such vital questions as why humans can talk and chimpanzees cannot, and why walking on two legs allows both laughter and speech, and whether you can tickle your cat.
An early chapter explains that people rarely laugh when alone, often laugh during conversation, women laugh more often then men, women laugh more often when they are conversing with men, and men seek out women who they can make laugh. The author discusses the cultural implications of this, and certainly this information makes me much more self-conscious at parties.
The author covers many disorders and their effects on laughter, such as autism, split brain, laugh epidemics, kuru (the laughing death), masque manganique, Angelman disorder, epilepsy, ALS, schizophrenia, prefrontal lobotomy, Rett disorder, Williams disorder, Alzheimers, and brain tumors. The end of the book explores whether 'laughter is the best medicine.' It's clear that there is no evidence to support this hypothesis, although the author still supports increasing the laughter in life by providing ten tips.
