Definition

A parasite is usually defined as an organism that lives in or on another organism, called the host, from which it gets its food and sometimes shelter. The word "parasite" comes from an ancient Greek word that literally means "a person who sat down to dinner uninvited". The parasite is always harming the host by slow or fast eating out of house and home. If it eats and grows fast then it becomes know as a disease or plague. If it eats slow we currently don't pay that much attention and accept all kinds of degenerative diseases as normal old age. We accept death at 60-80 and think that is normal when it could be at least twice that.
