GOOD: A new graphic novel about a man's journey to the Amazon to find his mother ... and study the human microbiome.

University of Guelph researcher David Good grew up in Philadelphia.

'GOOD: From The Amazon Jungle To Suburbia & Back' is a new graphic novel that tells David's story.

He went deep into the Amazon to reconnect with his mother 20 years after she returned to her home and left him with his dad.

He tells us how his study of the gut microbiome of his people, the Yanomami, is helping him learn about himself. Listen to CBC Radio Segment here.
