Problem: Text: The environment of the nose and the dried secretions removed contain many microorganisms. When a person is contagious with a cold, flu or other virus, it is important that hands or other objects used to remove mucus are washed promptly because there is risk of introducing microorganisms to other parts of the body or other people since it is a norm to handshake in most societies. When a person is not contagious, the act of picking and eating one's own nasal mucus can be therapeutic in that it may provide immuno-health benefits, as stated above. Friedrich Bischinger, an Austrian doctor specializing in lungs, advocates using fingers to pick nasal mucus and then ingesting it, stating that people who do so get ''a natural boost to their immune system''.
