Water is very important.We can live more than two week without food.However,we can only live for eight to ten day without water.Water goes around our body through blood.It carries oxygen and food for cells.It cleans our body and brings the waste in sweat or urine.It also keeps the balance of minerals in our body.Most parts of human body use water to work.We cannot move well if there is not enough water in our body.
65 % of our body is water.To keep that amount of water in our body we must drink an average of eight to ten glasses of water each day.How much water does a person need everyday ? it depends on the volume of urine and sweat.An athete who does a lot of physical exercise certainly needs to drink more water than a bank manager who spends most of this time in office.Beside drinking, many kinds of food are also a good source of water.Fruit and Vegetable,for instance,is eighty to ninety five percent water.(healthy,yuki)
