Shitting where you eat

There's an old addage that one should not shit where one eats. The implication is that to stay healthy and avoid disease born by the gastric workings of one's body, one should remove oneself from one's dining vacinity when defficating. Enteric bacteria which constitute 90% of mass of fecal matter can cause severe sickness and disease, thus there is truth to the addage.
Like much wisdom we as humans garnered over our many years of close contact with our environment, many people seem to have lost the implications of this old addage. Yes, modern technology and civil engineering have removed our defecant from our dining rooms, but the addage still hold true. Not only have people become too lazy and irresponsible to care about the condition of their direct living environment, but social responsibilty has allowed us to polute our only planet, essentially poisoning our selves, our mothership and our life force. This however is not purely an environmental rant, because in addition to the crap our modern chemical lifes spew, we produce plenty of mental, spiritual and emotional crap with which we poison ourselved and our relationships.
As I've said before and more than likely will say again, I belive the solution to this situation is a combination of personal actualization, personal responsibility and honesty. It is only by knowing oneself and the impact that one can have on their own life situation and the lives of those with whom we surround ourselves, either directly or indirectly, that we can really hope to improve the life of everyone. Selfishness and materialism will yet be downfall of you society if we let it. Only by accepting our individual roles as part of a functional society and realizing that our actions have greater implications, will we learn to respect the wisdom of those who told us not to shit where we eat.
