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.
How long you can survive without water also depends on how much total body water content you have. Total body water varies by age, gender and body fat. Men's bodies are composed of about 60 percent water, and women's bodies are composed of about 55 percent. Babies' bodies are composed of about 78 percent water.
