"Humor Seriously" by Jennifer Aaker and Naomi Bagdonas argues that humor is a powerful tool that can be used to improve our work and personal lives. The authors explore the science of humor, explaining how it impacts our brains and behavior, and offer practical advice for incorporating humor into our daily routines. They use examples from business leaders and comedians to illustrate how humor can be used to improve communication, boost creativity, and increase productivity. The book also discusses the importance of using humor ethically and appropriately, with consideration for cultural sensitivity and the potential for misunderstandings.
