In a sparkling debut in the entertaining pop science vein of Mary Roach, scientist Emma Byrne examines the latest research to show how swearing can be good for you. She reveals how swearing has been around since the earliest humans began to communicate, and has been shown to reduce physical pain, to lower anxiety, to prevent physical violence, to help trauma victims recover language, and to promote human cooperation. Packed with the results of unlikely and often hilarious scientific studies― from the "ice bucket test" for coping with pain, to the connection between Tourette's and swearing, to a chimpanzee who curses at her handler in sign language—Swearing Is Good for You presents a lighthearted but convincing case for the foulmouthed.
