Up to 90% of all organisms have a predominantly body water weight. Up to 60% of the human adult(man 21 years old weighing approximately 80 Kg)body is water. There is15.8% of your total water just on the brain and in the heart 73% of your total water, and the lungs are about 83% of your total water.

Therefore it is accentual to keep hydrated to prevent 'heat stroke'!
