Water and our Bodies A person can only live for a few days without water. 83% of your blood is water. Your bones are 70% water.
How Much Water? It takes 2 400 litres to process a quarter pound hamburger, 7 ½ L to brush your teeth, 26½ L to flush a toilet and about 95 -190 L to have a shower. The amount of litres of water needed to make 4 new tyres for a car is about 7853 litres.
Water in the Olden Days During medieval times a person used only 18.95 litres per day. Ancient Egyptians treated water by siphoning water out of the top of huge jars after allowing the muddy water from the river Nile to settle. Hippocrates, the father of medicine, directed people in Greece to boil and strain water before drinking it.
