  All life came from the smallest micro-organisms. These all developed in time, some less than others. All life is a competition – each organsism needs to compete for space and food. Bacteria (our germs) are competing for food by feeding off of (or near) us. Sometimes this does us harm (pathogenesis), sometimes helps us (symbiosis).
  If you were a germ or bacteria, what kind do you think you would be?
