Yesterday, ABC News Chief Health and Medical Editor Dr. Richard Besser took time to express gratitude in the form of a tweet chat.

The chat covered what the science says about gratitude: It can improve everything from emotional state to quality of sleep to heart health.

Check out some of the highlights from this gratifying social media conversation. And Happy Thanksgiving from the entire ABC News Health team.
