    FALSE:::::::: Up to 60 percent of the human body is water, the brain is composed of 70 percent water, and the lungs are nearly 90 percent water. About 83 percent of our blood is water, which helps digest our food, transport waste, and control body temperature. Each day humans must replace 2.4 litres of water, some through drinking and the rest taken by the body from the foods eaten.

    Water is of major importance to all living things; in some organisms, up to 90 percent of their body weight comes from water. Up to 60 percent of the human body is water, the brain is composed of 70 percent water, and the lungs are nearly 90 percent water.

    true and false some people have 10 percent and some people have 98.9999999999999999999999999999999999999999999999999999% believe it or not it depends on how many times a day you use the toilet. if you use it around 4-7 times a day you have only about 20-28% water. but if use use it 10-30 times a day you have about 60-68% 35+ times you have almost 100 percent water in you body!

      If your body is almost 100 percent water you might be a jellyfish

    From wikipedia:

    For example a cell of Escherichia coli contains 70% of water, a human body 60-70%, plant body up to 90% and the body of an adult jellyfish is made up of 94–98% water.

      Probably true, considering atoms are mostly empty space. People are mostly made of nothing, especially the brains of those who answered above.

    False Almost All of you are false for one not just tomatoes carry 90% water in their "bodies". Jellyfish actually contain 85%-98%. By weight, the average human adult male is approximately 65% water.However, there can be considerable variation in body water percentage based on a number of factors like age, health, weight, and gender. In a large study of adults of all ages and both sexes, the adult human body averaged ~65% water. However, this varied substantially by age, sex, and adiposity (amount of fat in body composition). The figure for water fraction by weight in this sample was found to be 48 ±6% for females and 58 ±8% water for males.

    The body water constitutes as much as 75% of the body weight of a newborn infant, whereas some obese people are as little as 45% water by weight.These figures are statistical averages, and so like all biostatistics, the estimation of body water will vary with factors such as type of population, age of people sampled, number of people sampled, and methodology. So there is not, and cannot be, a figure that is exactly the same for all people, for this or any other physiological measure.

    The human body contains 60-70% water... so FALSE!

    False. 60-70% of the human body is water. If this were true, there wouldn't be much of bones left after all water evaporate. proof: mummies bones, tissue, skin are still there, even after all water is evaporated! sad to see that still some people say this. ex: in documentaries such as Down the Rabbit Hole Documentary, where Dr. Emoto water experiment is explained, a lady said "90% of our body is made of water!" Hey! We're not jelly fish!

    false

    human body has 70%of water

    only tomato contains 90%of water and humans are not tomatoes

    I read that our bodies contain 90% of water fluid. All of which is contained in our bodies cells, spinal fluid, cerebral fluid, bones, lungs, muscles and blood. I guess most people only consider how much water is in our bodies but they don't think about where water goes in our bodies and what it becomes. Interesting research.
