People synchronize heart rates while listening attentively to stories

People often unconsciously synchronize bodily functions like heartbeat and breathing when they share an experience, such as a live performance or have a personal conversation. According to a new study, subjects' heart rates synchronize even if they are just listening to a story by themselves, and this synchronization only occurs when the subjects are paying attention to the story.
