Since We Like Labeling Good and Bad...
We should do this with the microorganisms in our body. We should take the labeling of good bacteria and bad bacteria one step further. We should try to kick out all what we perceive as bad bacteria and see what happens to the human body. If you would like to know the result, look no further than bad cholesterol and see how well that's worked out in modern medicine through pharmaceutical intervention since they've labeled it and attempted to treat it. If anything was ever inherently "bad" inside the human body, and part of the human, you wouldn't be born with it. Or would you? You decide.
