Here's today's feel-good story:
The human heart does not beat in a perfect rhythm due to changes in physical activity, and the fluctuations in beats can measure almost entire seconds.
Heartbeats of those that are listening to a story told by a storyteller can actually beat as one. This can also be the case when multiple people watch films together as well. These instances occur because we are shifting into "pay attention and remember" mode.
This experiment was done by presenting subjects with a 1-minute audiobook sample of Joules Verne’s20,000 Leagues Under the Sea. They found that there was a significant correlation of heart rate synchronicity between subjects.
