How Does Billion-Year-Old Water Taste? 'Terrible' A scientists takes a sample of water from a mine deep underground in Ontario, Canada. The water turned out to be 2.6 billion years old, the oldest known water on Earth. Credit: B. Sherwood Lollar et al. Last month, scientists announced they had found an ancient pocket of water buried in a mine 2 miles below Earth's surface. The water, up to 2.6 billion years old, may have been around longer even than multicellular life. The find raises intriguing possibilities for understanding how life arose on Earth and if it could survive on other planets. But the really burning questions is, of course, what does it taste like?

- Nowadays, it is very difficult to find rocks older than 3 billion years old, about 1.5 billion years short of the Earth's age. About 71% of the Earth surface is covered with water. Earth is the only planet where water can exist in liquid form. The presence of large amount of water also helps to regulate the temperature.

Mystery of Earth's Water Origin Solved The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.

- The Water Cycle. Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75% of the Earth’s surface. Geologic evidence suggests that large amounts of water have likely flowed on Earth for the past 3.8 billion years—most of its existence.

- As Adults our total body water decreases to about 60%. By the age of 60 years the our total body water (TBW) decreases to about 50%. As we age... we dry out. Cerebro-Spinal Fluid (CSF) surrounds our brain and spinal cord. A mere 140 ml of fluid bathes the brain and fills the ventricles (internal cavities of the brain). This Cerebro-Spinal Fluid replenishes itself 3-4 times each day.
