WATER AND HUMANS. * The human body is more than 60 percent water. Blood is 92 percent water, the brain and muscles are 75 percent water, and bones are about 22 percent water. * A human can survive for a month or more without eating food, but only a week or so without drinking water.
Babies have the most, being born at about 78%. By one year of age, that amount drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water. Thus: 1  Babies and kids have more water (as a percentage) than adults. 2  Women have less water than men (as a percentage).
