Hi people, I need some ideas. There have got to be million things but I'm looking for some of the most likely. There can be virus, bacteria, fungus, heavy metals, industrial poisons and chemicals(is there any we to test for a whole lot of these?) Any other ideas? Most things foreign to the body, it will usually purge by itself right? Well what is something that could get in probably by the digestive tract that the body may have trouble getting completely rid of?
