In this episode I discuss Synesthesia. What is it? How common is it? What is it like to have it? I review the many different types of Synesthesia and describe each of them. I cite two medical articles about Traumatic Brain Injury (thru Stroke) and Synesthesia. People can be born with Synesthesia but people can acquire it thru a variety of ways. So if blue number 10,547 makes you happy then please join me for this very interesting episode.
