Water is a essential molecule for our body. About 98% of our body is made up of water. Humans cannot survive if their normal water content lessens below 12%; hence the homeostasis of drinking water is an important mechanism. Water has many important functions in our body. Water serves as a transport medium in blood vessels and secretion e. g. in digestive juices, tears. Drinking water is an excellent lubricant and serves to reduce friction when combined with particular proteins e. g. mucus to assist external motion. Many chemical reactions take place in an aqueous medium (Jones M. et al. 2000) The kidneys are highly specialised organs of your body and play an important role in homeostasis. Fig 1a shows the positioning of the kidney in the body. The kidney sustains homeostasis by regulating drinking water balance, spend removal and blood vessels structure and pressure.

Middle adulthood is the period of time from 35 years of age until 64 years. It is the midpoint of someone's life. Many folks have achieved happiness at this point in their lives, but there are some who feel like they are very much closer to death without accomplishing anything.

Webster defines middle as "equivalent distance from the beginning to the finish" (Dictionary, 2010).
