Six minutes without oxygen to the brain and you are dead. That’s all. Six minutes. Doesn’t matter if you are 80 years old or 8 days old–you’ve got six minutes. My take away from AED/CPR training this morning is that oxygen is very important.
Take out your favorite candle. Light it. Wait until it is burning well. Then take a metal snuffer and place it over the wick. In less than 10 seconds, the fire is out. Fire needs oxygen to burn anything. No oxygen, no fire.
Oxygen, “O-Two” as the chemists call it, is so simple but so necessary. It took thousands of years for humans to even know that oxygen existed. We can study chemistry and know that is exists, but do we really understand it? I think the only humans that can really understand oxygen and are still living are the astronauts. When you are up in space and there is no oxygen except for what you have stored on board the shuttle or space station, you must become highly aware of what oxygen means and what it is.
That is why I think many of the quotes of the astronauts who have been in outer space mention our good God: “To look out at this kind of creation out here and not believe in God is to me impossible, … It just strengthens my faith. I wish there were words to describe what it’s like.” – John Glenn
I think oxygen is like the breath of God in a way. It sustains our lives. It kindles fire. It is all around us whether we choose to recognize it or not. It is.
