Stay Germ! Staaaaaay... Staaay... Good Germ!

What!?!  Good germs?  Well... the bacteria we have on and in our bodies are like pets in a way.  We benefit from them and they benefit from us.  Like a good guard dog, good bacteria keep the bad bacteria from moving in and making us sick.  Immediately after birth, bacteria begin to grow in our intestines and on our skin.  This bacteria helps stimulate the immune system, and even help digest food in our intestines.  Some bad germs live on us all of the time, but only make us sick when our immune system is weakened.  These are callled opportunistic infections.  Like a single knight attacking a castle, one bacteria has little chance of hurting us... however, a million or even a billion knights attacking a castle are reason for some concern for unwary castle inhabitants.  Disease is arguably only a side effect of germ growth and reproduction.  So, germs aren't inherently bad and they don't have brains, they just want a place to eat and reproduce.  It is often the germ byproducts that make us sick.Stay Germ!
