You must have heard about Joe from old Reader's Digests and old English textbooks. You know, the series of articles where the human (Joe's) organs describe and speak about themselves. But truth be told, it's seldom the whole truth over there. Let's just say, Joe isn't your average Joe, he does stuff. Secret Stuff.
No other organ in Joe's body can equal me. No larger than a Beer-Pong ball, I have millions of electrical connections and can handle 1.5 million simultaneous messages. I gather 80 percent of all the knowledge Joe absorbs, 80% of THAT knowledge makes me sleepless at night. He thinks of me as a miniature Tv camera. I consider the comparison insulting. I am much more sensitive than the biggest, costliest TV camera ever made, but Joe gives more importance to his tiny bathroom-spy camera. I am responsible for one of the greatest of all miracles - Sight.
When he was young, Joe used to read magazines in dim light. His mother warned that he was "ruining" his eyes. Nonsense. The young see better in dim light than adults; and viewing under even the most adverse circumstances does no harm. That's what I thought, in reality, this gave him a heads up on life, magazines and uncensored pages. Now Joe's ruining everything except his eyes.
Nature gave me superb protection, placing me in a bony cavern with protruding cheekbones and forehead to act as shock absorbers for direct blows from, well, almost everyone Joe knows. She also gave me hypersensitive nerves to activate the alarm if there should be a potentially damaging intruder such as the smoke from his hashish and...wait a second, strike all that, hypersensitive when high? Who am I kidding! Period.
Both my cornea and my lens-normally totally transparent tissue--can cloud and lead to blindness. If it is the cornea, Joe can regain sight with a corneal transplant. If it is the lens, he will need a cataract operation, and either thick eyeglasses or contact lenses afterward. Fortunately, Joe has so far escaped all these diseases, but his disorder of winking at girls at bus stops is really gonna get him one day. Just the same, I am growing old--like Joe's other organs. The transparency of my lens is lower, accommodation muscles are weaker, hardened arteries are diminishing his already black blood supply to my retina. These processes will continue, but Joe should not worry unduly. The odds are heavily in favor of my providing him with serviceable vision as long as he lives. And hey, with the levels of impurities in his blood and his sizzling Lungs and liver, I think I'll be having a very early retirement.
