We all have parasites all the time. The secret is to keep the body healthy so those parasites do not get out of control The task is control not elimination. Colon health, good stomach acids,proper body PH is the key.When the parasites get out of control is when we fail to digest food properly and that partly digested food serves as a parasite banquet, then the downward spiral begins usually taking years for disease and death to appear.There are parasites that live in the blood and invade blood cells that are controlled by enzymes and white blood cells, those enzymes diminish with age and poor digestion creating an aged body. Digestion is everything. Death occurs when the cells fail to reproduce themselves faster than they are dying. Change this fact and death will not occur, delay it and you can live to 120.
