Pus

A discharge of plain yellow pus cannot be counted as a plus. If tiny micro-bugs turn mean they gurgitate the colour green. That gives the body one good reason to counteract this shameful treason. You see, we humans are too kind, we have been given a good mind and understand how illness kills, and have invented many pills to stay alive, avoid infection chase bugs into a new direction. When simultaneously one feeds whole colonies to meet their needs it is too easy to forget that most of them you've never met. Thus, it is my considered view that coughs, pneumonia and the flu could be avoided altogether regardless of the ambient weather. Our bloody hospitality is for disease the master key. So, don't invite or tolerate those pathogens to tempt your fate. And do apply, likewise a ban to hucksters and the bogeyman.
