Seriously, Ian you need to attend to another matter until you become a visiting lecturer or visiting host for Coast to Coast. You need to provide training tools or a lesson plan on how to be engaging, humorous, thought-provoking, entertaining, darned good, and just simply how to read a book type host, to anyone every considering taking a paranormal or mysterious universe type show and hosting it. Your input is valuable, and just like Art, those shoes cannot be filled to the same exact fit.
I just read the above post, and have to add this. Modern medical science is making amazing strides. Also, prayer and mass consciousness could be of use here.
This may just be a hiatis. You never know!
