All that time I thought the fish were the cool ones.  If you go back in time, the first organisms were itty bitty tiny micro-organisms. They lived in water, its the only place they could survive. These micro-organisms evolved into fish... but they could still only survive in water. As evolution continued, creaters began to survive longer and longer outside of water. Outside of water, the environment was hash and animals such as fish would shrivel and dry up. Eventually, animals that lived solely on land evolved. These creaters had a dry skin as compared to fish's scales. This skin helped keep water inside the body.

The human body is made up of approximately 70% water. We cannot survive without water.  We do not live "in" water, so we evolved and essentially brought the water with us. Our bodies are like a reservoir, keeping the necessary water for survive with us and keeping all our bodily functions running smoothly. But like any other reservoir, we must renew our supply. To renew our water supply, we need to drink water every day. The world's water supply is in sad shape. Nearly a billion of the world's population is denied access to safe drinking water.

Safe drinking water is important for all human functions. Our skin, muscles, fat, eyes, organs, blood; everything needs water to do its job.

Fish, like humans, need water to survive. They live in the water to survive. We have adapted our bodies to hold the water we need to survive. I guess we're the cool ones instead.
