Secrets and magic

Is every 3 year old obsessed with these 2 things?  Ben loves to tell secrets - in his mind, everything should be told in this form, regardless of how unsecretlike the subject matter is.  And then there's magic.  Anything that is cool or difficult to understand is "magic".  An airplane in the sky?  Magic.  A science experiment?  Magic.  Batteries and magic are an explanation for everything you know.  Don't bother trying to tell him different, he's very sure of himself.
