Chapter 5 - Different Approaches to Hydration Chapter 6 - Minimising Water Loss Conclusion Author Bio Publisher Introduction Nothing, I repeat nothing, is more important than water for humans to live on this planet (well excluding oxygen though that's obvious). Your body is made up of around 60-80% water and you cannot hope to continue performing your daily chores with the same efficiency if you don't find enough water. Certainly the amount of usage of water varies depending upon the climate and activities you are involved in, but its presence is always required. In a moderate climate with low levels of activity, approximately 2 liters of water is required daily for a 160 lb person. Certainly when the climate changes or the level of activity turns to exercise, you need to increase this amount simultaneously. The first sign of dehydration may be discerned through the color of the urine. A normal hydrated body produces a pale yellow color, but a dehydrated body produces urine that is darker in color. To make sure that the body doesn't dehydrate you need to not only meet the required quantity of water, but you also have to make sure that the water is clean. The reason why you constantly need to drink water is because your body continuously releases liquids and you need to maintain those levels. The release of liquids from your body is in the form of urination, sweating, excretion, and respiration. The liquids are released so that the toxins can be removed from your body and proper hydration makes this happen along with redistributing the nutrients in the body. Water also provides the pathway for electrical impulses to travel through nerve and brain cells to activate the muscles. The brain in itself is made up of 80% water. Contributor Bio:  Davidson, John John Davidson was born in Barrhead in Renfrewshire in 1857. He spent his childhood years in Greenock, and after working as a pupil-teacher and briefly attending Edinburgh University, taught in schools in Glasgow and Perth. In 1989 he moved to London where he made his living as a journalist and critic. Several dramas had been published while he was still in Scotland, but in the 1890s he turned to poetry, and published several collections which were very popular: In a Music-Hall (1891) and Ballads and Songs (1894) amongst them. These were poems which chronicled urban working class life, and his sense of outrage at the poverty of the ordinary man, as expressed by the much-anthologized 'Thirty Bob a Week'. At the beginning of the new century he moved away from the lyric and began writing in blank verse which incorporated much scientific language; this series of Testaments were not as successful as his earlier ballad style, though Hugh MacDiarmid was to pay tribute to Davidson's attempts to combine poetry with scientific ideas. Despite the early popularity of the poetry, financial difficulties constantly plagued Davidson; he had had no choice but to continue with the journalism he disliked in order to support his family and other dependents. Sadly the money worries, combined with ill-health and depression, drove him to committing suicide in 1909.
