INDIANAPOLIS, Ind. (Nov. 5, 2015)-- Stevie Wonder has an extraordinary sensory condition called synesthesia. He can taste and smell sound. Billy joel has it too.
Synesthesia is when the senses come together instead of staying apart. For instance, people can see numbers or letters in color. Sometimes they experience taste, when it normally should be sight.
It's a documented neurological phenomenon. It's estimated one in every 300 people have some variation of synesthesia. Doctors are still trying to figure it out.
Babies are thought to have synesthesia. Scientists believe when an infant hears her mother, she may also be smelling and seeing her. Most grow out of it.
For those who have it, some experts say to go with it-- the rest of us are missing out.
It was a blessing for artists like Billy Joel and Stevie Wonder, and we've all benefited from their gift.
