But then, with every step we take, we begin to dry. The longer we live, the drier we get. One year after birth, a human baby is only 65 percent water – a ten percent drop, says the U.S. Geological Survey.⁠
Babies are wetter than children. By the time we're adults, the USGS says, adult men are about 60 percent water, and adult women are about 55 percent. Elderly people are roughly half water.⁠

There are variations, of course. The more buff you are (muscle tissue stores more water), the wetter you are. Because women generally have more fat cells, they tend to be a bit drier. Fat cells aren't as moist. The water that lubricates your joints, flushes your waste, assists seminal reproduction, and absorbs shocks to your bones — as you age, the moisturizer in you slowly dwindles.⁠
And the odd thing is, our wet parts aren't where you'd think.⁠
⁠
Our brains, lungs, hearts, livers, and kidneys contain the wettest tissues — between 65 and 85 percent water. Bones, of course, are dryish (but still 31 percent water). There's also water between cells, but only a small fraction of our H2O is blood. Most of the water inside us is stored, not in our veins, but in our 100 trillion teeny cells.⁠
