Podcasting - The Perfect Podcast Guest

The perfect podcast guest is one who answers the questions, but also understands that they are the expert, not me. There's a perspective that youth and energy and vigor bring that is not going to be there the older people. I would like more hits than missus. But the excitement, the unpredictability, that's all part of the fun. Do you think someone who did not do well in school and has barely used math in decades should re start at pre algebra, say, rather than dive into a more interesting ad subject?
