I'm a geophysicist and all my earth science books when I was a student I had to give the wrong answer to get an A. We used to ridicule continental drift. It was something we laughed at. We learned of Marshall Kay's geosynclinal cycle which is a bunch of crap.
I actually may do a musical next year... not one that I've written one that I may star in. Plus my concert and other people's work and all of a sudden you've got a very full life.
