Questioning Immune Chaos

"The first Law of Chaos: There is no law. And Anarchy's its cousin."

Thus said my immune system, one fine day... after 30-something years of blissful obedience.

And so I wonder... What would make the immune system go mutinous? And why? Is there an external trigger, like stress, or burning Twin Towers? Or is it more of a post-embryonic, tasteless joke -- like a congenital cyst that pops up in the middle of one's forehead one day while reading in the library? Could it be recessive genetics? Perhaps I am the dumping ground for all of the bum genes in the clan. Or could it merely be the way this particular body has chosen to enter mid-life? 

Genetics can tell us of someone's predisposition to develop conditions, but it does not necessarily dictate destiny. Pollen allergies are the precurors to food allergies... but not everyone with a pollen allergy develops food allergies. So what are the determining factors? Do the effects of nature make their way into our genetic encoding? Post-mortem, do our genes look exactly as they did at birth? And in what way does aging play a role? 

Fifty years ago, kids brought peanut butter and jelly sandwiches to school and shared them without a care. Two hundred years ago, kids ate raw peanuts. Today, peanut butter is not admissable in schools... And more and more people are living the reality defined by celiac's disease. Which begs the question... How are the younger generations different to their ancestors? Is it the environment? Modern agriculture -- the way we grow or raise our food? Or could it be the manufactured food industry? When last have you eaten a packaged food product that had less than six ingredients, none of which had more than three syllables? Or could it be something our parents used -- medications, creams, ointments, water -- something that seeped into their systems and into their gametes? 

Health providers understand the scientific mechanics of the body's immune system, but they don't understand the spirit of it -- the why it does what it does, the way it does it, bloody well when it decides to do it. Perhaps in 300 years, the barriers between scientific disciplines will have been eradicated. Maybe then they will be able to explain the nano-science of the neurotransmitters that relay the instructions to go haywire. Quantum Physics' mischievous conspiracy with Physiology... But will they ever be able to explain how the instructions were conceived and constructed?
