Messier81GalaxyThis (???) is often no need to leave my room.  My music is here.  Each note, each song, each LP, CD and the cassettes I have put together from my vast music collection, they are all universes within universes.  That does not even mention the many books on my shelves.  Then there are the birds I view when the sun comes up and spend hours doing so.  I never have to go too far to explore the next universe.  My mind roams all the time.  And that is just one large room in this house.
