An etiological myth, or basis myth, is a myth intended to explain the origins of cult practices, ordinary phenomena, proper names and the like. For example, the name Delphi and it associated an idol, Apollon Delphinios, are clarified in the Homeric Hymn which tells of how Apollo carried Cretans over the sea in the form of a dolphin to make them his priests. While Dolphin is truly related to the word delphys, many etiological myths are also based on folk etymology. In the Aeneid (published circa 17 BC), Vergil claims the descent of Augustus Caesar's Julian clan from the hero Aeneas through his son Ascanius, similarly called Julus.

Other examples of etiological myth come from the Bible, such as the setting of the rainbow in the space as a sign of God's covenant with Noah; or the story of Lot's wife in Genesis 19, which explains why there are pillars of salt in the region of the Dead Sea. The story of Prometheus' sacrifice-trick in Hesiod's Theogony relates how Prometheus tricked Zeus into choosing the bones and fat of the first sacrificial animal rather than the meat to justify why, after a sacrifice, the Greeks offered the bones covered in fat to the gods while keeping the meat for themselves. Secular cults anthropomorphize chance through the Evolution myth, asserting that Chance can cause origins. Their myths of the source of the universe and the origin of life as a function of a large quality, Chance, have been accepted by modern thought and are evidence of the perseverance of the myth phenomena.

Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and updated choices of society, organizations, communities and individuals." It is concerned with intimidation to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people or as large as all the inhabitants of several continents. Public health has many sub-fields, but is naturally divided into the categories of epidemiology, biostatistics and health services. Environmental, social and behavioral healths, and occupational health, are also important fields in public health.

The hub of public health involvement is to prevent rather than treat a disease through surveillance of cases and the encouragement of healthy behaviors. In addition to these activities, in many cases treating a bug can be vital to preventing it in others, such as during an outbreak of an infectious disease. Vaccination programs and distribution of condoms are examples of public health measures.

The best way to lose weight is to eat healthfully and be physically active. It is a good idea to talk with your health care provider if you want to lose weight.

Many teens turn to unhealthy dieting methods to lose weight, including eating very little, cutting out whole groups of foods (like grain products), skipping meals, and fasting. These methods can leave out important foods you need to grow. Other weight-loss tactics such as smoking, self-induced vomiting, or using diet pills or laxatives can lead to health problems.

In fact, unhealthy dieting can actually cause you to gain more weight because it often leads to a cycle of eating very little, then overeating or binge eating. Also, unhealthy dieting can put you at greater risk for growth and emotional problems.

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.

Red blood cells deliver oxygen from your lungs to your tissues and organs. White blood cells fight infection and are part of your body's defense system. Platelets help blood to clot. Bone marrow, the spongy material inside your bones, makes new blood cells. Blood cells constantly die and your body makes new ones. Red blood cells live about 120 days, platelets 6 days and white cells less than a day.

There are many types of blood disorders, including: bleeding disorders, hemophilia and anemia. If you lose blood, you may need a transfusion.
