Oxygen is my favorite element because as you can see
without it, we would die. People say that they are starving when they haven't eaten for
two hours, and that they are thirsty almost five minutes after they had a glass of water.
Well, the fact is, you can live weeks without food, days without water, but you can only
live five minutes without a breath of oxygen. When you are asleep many people think you
don't get much oxygen. They are WRONG! As a matter-of-fact, a resting person consumes five
gallons of oxygen every hour he sleeps. So, if you slept eight hours you have just
consumed 40 gallons of oxygen. Here is something even more strange. People think the
air is 100% oxygen. That is also wrong. Air is filled with Carbon Dioxide, Argon,
Neon, Radon, Helium, Krypton, Xenon, Hydrogen, Methane, Nitrous Oxide, Ozone, 4% Water
Vapor, Dust, Smoke, Salt, Carbon Monoxide, and Microorganisms. That is a lot of substances
in the air we breathe.
