It does make sense, but in life five years is actually a big segment. When you're done with this project, where does that lead? I hope you're thinking of compiling the podcasts into a book and that you're already talking to publishers, for example. I'm at the endgame of my career and I'm glad I listened to my elders who kept saying, “think about retirement now!” If you haven't read The Ascent of Man, you may wish to do it now. It's podcasts for the pre-podcast era. The book and the television series did well for its author. Maybe a deal with NPR or BBC? You have enough podcasts in the can that they might want to pick it up.
