When it comes to humans, our brains and hearts are composed of around 70 percent water, while our lungs contain a whopping 80 percent.
Even our bones are about 30 percent water. To survive, we need close to 2.4 liters daily on average,
some of which we get from food.
The average is around 68% water.
