Rather, that garbage attracts the flies. Further, that if you kill the flies, the flies will return as long as the garbage remains. So it is with the human body. This is obvious in that bacteria like streptococcus, tuberculosis, pneumonia, etc., are present all around us and throughout our bodies, and yet we are not always sick. Healthy cell tissue, like the fresh fruit in Louis Pasteur's experiment, offers the bacteria nothing to feed on.
All bacteria are scavengers.
Like flies, bacteria eat ONLY dead, toxic, rotting or decayed tissue. For example, colds and fevers are NOT caused by germs.
