The human body secretes many substances, some more pleasant than others. Such substances help us break down our food, display our emotions and expel waste. While production of these fluids is generally easy to predict, recent years have seen an increase in the amount of saliva produced by some people. This trend has required these people to spit the excess saliva in the street, surely an embarrassing affliction for those thus affected. Certainly saliva plays an important role in our lives, but its time is surely better served within the human body rather than outside of it.
For the rest of us this means we need to remain ever vigilant to the random expulsion of saliva from individuals who are abundantly rich in saliva. This forced exit of saliva from the body is something which cannot be prepared for, it can happen at any time and in any place. Innocent bystanders or pedestrians may suddenly find themselves having to duck and weave away from a direct saliva strike, or they may have to avoid walking in the resulting drops of saliva which fall on the ground from those who spit. In any case, the simple act of walking down a street now requires much concerted observation.
Unlike other bodily substances the over-production of saliva seems to be a worsening epidemic. It is an area which medical science has often overlooked but surely now should turn its eye to work towards a modern and technologically advanced solution.
For those suffering from this condition, society extends its sympathy. However until a cure presents itself perhaps you could manage your problem more discreetly and not cause other people to suffer from your unhygienic practices.
