A nourisson is composed of 75 % of water whereas an adult does not have any that 65 %. an old person do not have only 59 % of its weight in liquid form. Entirely dehydrated, a man of 80 kg would weigh nothing any more but 30 of them. Sapiens indeed consists of 65 % of water approximately. But it is nothing in comparison foetus of two months which contain 97 % of them, that is to say 2 % less than them... jellyfishes. 400 million years passed since the colonization of the firm ground through our very remote ancestors and we always depend on water!.

Our brain contains 80 % of them, our muscles 75 %. One find water until in our bones (30 %) and our cells which, all unit store half of the water of the organization (27,5 liters approximately at a man of 80 kg). The molecule there transports ions and proteins, or intervenes in chemical reactions which make it possible the cell to manufacture its energy. The spermatozoïdes swim to the ovule, l’embryon develops in a pocket of water, our eyes are maintained by our tears...

Pulled about by thirst as soon as the quantity of water decreases in the organization, we drink. More than 35 000 liters during a life... which we will spend 106 days complete to eliminate (by way of comparison, to go to the school up to 16 years does not take that 450 days of 24 H). It is thus necessary to have the solid kidneys. Each day, the latter filter 12 times the interstitial water of the organization (that which does not form part of the cells). A large breakdown of the kidneys and water accumulates in the form of oedema in a member, or worse, in the brain, plunging its owner in the coma.
