So no compulsory classes at all in school? How is one to find out which subjects are stimulating and which are not without some introduction to them?

Whilst rocks are fascinating to some, I'm not sure the analogy holds as rocks are not (more than they ever have been before) becoming a part of everyone's everyday life.

If we were living in the stone ages I would be arguing for compulsory intro-to-rocks courses :)
