I've suggested this guy before but i now see he has a book out (as well as a nice summary on youtube: https://www.youtube.com/watch?v=5k6NrrXbTpU), just so you know he has enough material for a show (I'm almost certain he has enough for 3-4 shows). It's definitely not your usual alternative health info, in fact it runs counter to a lifetime of indoctrination, which is why I think it'd be perfect for THC. I know it's not really your thing but I reckon it'd make a great show!!
