Where do worms live in humans? If we are lucky, they live in the intestines in small numbers and stay there without causing much harm. However, in a good number of us, for whatever reason, the worms will leave the intestines and begin to crawl around in the body, get into the lymph system, or their eggs will get carried somewhere else in your body by your bloodstream. Note that if you have parasites in the lymph system, it'll make every disease much worse because now you cannot defend yourself properly, and it will also cause inflammation as the antibodies are constantly trying to kill off a bacteria or virus that is actually living on something much bigger---a worm. Additionally, for someone with cancer or a dysfunctional immune system, you especially want to keep the lymph system clear, else you will be prone to infection. In the case of a parasite infection, the worms can go to the lungs causing problems, the heart and cause distress, endocrine organs and make them malfunction, and even the brain, causing mental symptoms. At any rate, since worms live in just about all of us, why not purge the little boogers? You eat food, they eat your food, hey that's where part of your vitamins and minerals are going. When we fast, they begin to starve. They only want to do one thing in you: eat and reproduce.
