Joe Rogan was very entertaining, he surprised me with his range of topics covered. He is very opinionated, which makes for good comedy, and likely given his prolific drug use an addict -- so check again for good comedy. "Addictive Thinking" by George Koob comes to mind...addiction is a fascinating disease. If you think back on all of the great comedians, nearly all were addicts and in the best case definitely all would qualify for a mental disorder of some sort -- which correlates perfectly with comedy. Your thinking has to be different, which addictive thinking is...whether different is good is debatable, exactly what is normal? That Joe would definitely have an opinion on. Was a little lengthy, but all in all great value for the money.
