Q: There are reports of stingers breaking off in wounds, but this may be rare. This would not be fatal to the stingray as it will be regrown at a rate of about 1.25 to 2 centimetres (0.49 to 0.79 in) per month (though with significant variations depending on the size of the stingray and the exact species). Contact with the stinger causes local trauma (from the cut itself), pain, swelling, and muscle cramps from the venom, and possible later infection from bacteria or fungi. Immediate injuries to humans include, but are not limited to: poisoning, punctures, severed arteries and veins, and occasionally death. Fatal stings are very rare, but can happen, infamously including Steve Irwin. In Irwin's case, the stinger penetrated his thoracic wall, causing massive trauma.

Q: 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''.

Q: A travel document is an identity document issued by a government or international treaty organization to facilitate the movement of individuals or small groups of persons across international boundaries, following international agreements. Travel documents usually assure other governments that the bearer may return to the issuing country, and are often issued in booklet form to allow other governments to place visas as well as entry and exit stamps into them. The most common travel document is a passport, which usually gives the bearer more privileges like visa-free access to certain countries. However, the term is sometimes used only for those documents which do not bear proof of nationality, such as a refugee travel document.
