What we don't know

All that I am certain of is that I am here and it is now.  I am currently only human.  The senses that I possess are limited.  My eyes are unable to perceive the full spectrum of light and color vibrations.  My ears cannot detect the full range of sound vibrations. All other sense abilities are likewise limited.  What could all of these things be?  How do they interact with and affect the limited perceptions I AM aware of?  I can never, ever, ever, ever know.  I can be certain of nothing.  The mystery is bliss.  The endless adventure feeds curiosity, which voids all potential boredom.  And who wants to live forever, anyway?
