The sari (saree) is the most popular outer garment of women of the Indian subcontininent. It consists of a piece of silk, cotton or synthetic cloth, five to seven yards long which is worn wrapped around the body with the end left hanging (the pallu) or used over the head as a hood. The border of a sari is usually embroidered and this is often a status symbol. Also different regions of India have specific methods of wrapping the cloth. A short tight fitting blouse called a choli is usually worn under the sari.

Problems with excessive thinness

Being too thin can occur with anorexia nervosa, other eating disorders, or loss of appetite, and is linked to menstrual irregularity and osteoporosis in women, and greater risk of early death in both women and men. Many people -- especially women -- are concerned about body weight, even when their weight is normal. Excessive concern about weight may cause or lead to such unhealthy behaviors as excessive exercise, self-induced vomiting, and the abuse of laxatives or other medications. These practices may only worsen the concern about weight. If you lose weight suddenly or for unknown reasons, see a physician. Unexplained weight loss may be an early clue to a health problem.

Heavy, Sticky Oils

Oils are characteristically viscous, sticky or tarry, and brown or black. Flushing with water will not readily remove this material from surfaces, but the oil does not readily penetrate porous surfaces. The density of oils may be near that of water and they often sink. Weathering or evaporation of volatiles may produce solid or tarry oil. Toxicity is low, but wildlife can be smothered or drowned when contaminated. This class includes residual fuel oils and medium to heavy crudes.
