Why do corpses rot and living things don ?
Rotting is because bacteria and single cell organisms start growing rapidly. Our immune system is what kills off “bad” things before they reproduce so much that they make us sick. There are bacteria around us all the time and many of these would make us sick if they were allowed to reproduce uncontrolled. They say the most dangerous bite is to be bitten by a human. Sometimes, a virus or bacteria come along that our immune system does not respond to quickly enough. In these cases, we get sick, sometime very sick, and our immune system needs help to fight off these things. Antibiotics can help. Sometime, even living things rot. Some diseases cause the body to be unable to fight off infections and people get infected by, for example, gangrene. This causes your flesh to rot while you are still alive. If this is not treated (sometimes requiring amputation), it will kill you.
