Abstraction: when applied to dance, this word refers to choreography that does not have a narrative character. In other words, an abstract dance does not tell a story, nor is related to symbolic contents or any kind of associations with feelings, ideas or other elements than movement itself.
Facts about asthma. 1  WHO estimates that 235 million people currently suffer from asthma. 2  Asthma is a public health problem not just for high-income countries; it occurs in all countries regardless of the level of development. 3  Asthma is under-diagnosed and under-treated.
Asthma ranges from mild to severe. Some people have only occasional, mild symptoms. Others have nearly constant symptoms with severe, life-threatening flare-ups. During an asthma attack, the airways become more inflamed than usual. They narrow as the muscles surrounding them constrict. Mucus produced by the inflammation fills the narrowed passageways. As a result, the flow of air is partially or completely blocked. Asthma affects the lung's larger and smaller airways.
