When you hear the word 'addict' what do you think of? Is it someone injection heroin on the streets? Someone drinking cans in the middle of the day?

He joins Rachel via Skype to discuss his heroin addiction, rehab, how he turned his life around to become a neuroscience lecturer and researcher in Trinity College Dublin and writing his new book 'Bonus Time'.
