If we think of a baby in terms of chemical composition, it is a bag made of hundreds of millions of atoms.
According to Neil Shubin, author of “The Universe Within: The Deep History of the Human Body“, the chemical formula of a baby, the most numerous are the atoms of hydrogen and oxygen. Of course, since people are very “watery”, especially when they are born, this should not surprise us if we think that water consists of two atoms of hydrogen and one of oxygen.
A brand new human baby is 75 percent water.
So when a baby is born, its body is made up of 75% water. In other words, we are born less humid as a potato (which is 80% water) but leave behind bananas (having 74% water). Tomatoes are wetter (93.5 percent water). Apples, too, but only slightly (80 percent).
We aren’t as wet as watermelons, but still, we begin our lives as a noisy bag of water that will one day learn to crawl, then walk. Science writer Loren Eiseley said that people “are a way that water has of going about, beyond the reach of rivers”.

Aging = Drying
The longer we live, the more we dry. Specifically, only a year after birth, a baby’s body contains 65% water, 10 percent less than a year ago, indicating the U.S. Geological Survey.
Furthermore, mature men are 60 % water and 55 % women. As people age, they contain only 50 % of water.
Of course, the percentage of water in the body varies from one individual to another. For example, the more muscular you are, the more you are “rich” in the water. Also because, in general, women have more fat cells, they are a bit dry compared to men.
What are the parts of the body containing mostly water?
The brain, lungs, heart, and kidneys contain wet tissue. Specifically, these organs contain 65% water – 85 % water. Bones, which are quite dry, they contain 31% water.
Although we tend to think that most of the water is found in veins, in reality, it is stored in the 100 trillion small cells. We are a group of small packets of lightly salted water as the sea from which we came. After that, very quietly, the sea within us ebbs and ebbs, and as it goes … so do we.
