The human body is about 50 to 65 percent water.

Within single cells water content ranges between 70 and 85%. The percent water in the entire body by weight varies with age, sex, and physical conditioning. Heart and lung contain the most water, about 80%. Fat (about 20%) and bone (about 43%) are among the lowest. Therefore, the total body is an average of all organs, blood, and extracellular fluids. Several physiology texts place average young men at 60% water, and young women at 50% water, the difference due to relatively more fat in females. Thus, a 70 kg young man has about 42 kg (or 42 liters) or water. With age fat increases and muscle decreases, so that in old age the body may contain only 45% water. Infants, by contrast, average 73% or more.

Different people have different percentages of their bodies made up of
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. Fat men also have less water (as a
percentage) than thin men.
So you can see three possible reasons for the discrepancies you have found:
1) Babies and kids have more water (as a percentage) than adults.
2) Women have less water than men (as a percentage).
3) Fat people have less water than thin people (as a percentage).
A forth reason is that different people measure per cent water a little
differently, causing small differences in the answer.

55-75 percent is water.
take your weight / divide by 2.2 = the ounces of water needed to drink

The answer is very simple. Our body is composed of earthly elements derived from the soil. Anything that we consume comes from the soil. When one dies, the body decomposes and goes back to the earth itself, regardless of whether the body is buried or cremated. In short, your body becomes a part of the earth itself, becomes a part of soil.
