Despite what you might guess, when monitoring your breathing, your body doesn't care whether you're inhaling enough oxygen. It cares only whether you're expelling enough carbon dioxide - that's the gas that sets off the panic button when you're suffocating.

I could write a thesis on the physiology of vision. But I had no way to look through the fabric of confabulation spun by a man with severe lung disease who was prescribed 'home oxygen', but gave a false address out of embarrassment because he had no 'home.'

I witnessed a surgery on a patient from New Orleans who was in a car accident. He didn't have any flow of oxygen. He couldn't breathe. He couldn't get a good flow of oxygen, so they did a surgery on him right there, and I was just holding the IV up watching.

For a Westerner to trash Western culture is like criticizing our nitrogen/oxygen atmosphere on the grounds that it sometimes gets windy, and besides, Jupiter's is much prettier. You may not realize its advantages until you're trying to breathe liquid methane.

No one is ever better off with dictators but there comes a time you know, when you're on an airplane, they always say, "in case of an emergency oxygen masks will drop down. Put yours on first and then administer help to your neighbor." We need oxygen right now.

I believe that at the moment of death, that the soul is released in a molecular form, that actually goes into the - the fabric of the universe, the structure of hydrogen and nitrogen and oxygen because we're electrically - we're galvanic, we're electrochemical.

There is no water in oxygen, no water in hydrogen: it comes bubbling fresh from the imagination of the living God, rushing from under the great white throne of the glacier. The very thought of it makes one gasp with an elemental joy no metaphysician can analyse.

Standing on the apex of our planet is humbling. I'm starved of oxygen, depleted of reserves, unable to eat, and bound by anxiety. This is a dangerous place. Yet the symbolism of standing on top of the world gives me a chance to experience time on a cosmic scale.

They don't want to get dirty and they know that Trump loves this kind of thing. And your polls, and yours are what's giving them the material that they need, it's the oxygen that the Trump campaign requires, a poll every three or four days showing him where he is.

The blood corpuscles take up the atmospheric oxygen in the lungs, and the vital chemical process accordingly depends essentially on the combination of oxygen absorbed by blood corpuscles with the combustible constituents of the blood to form carbonic acid and water.

For a very long time, we've been extraordinarily interested in the interaction between low temperature and low oxygen. We see that they're connected because we know people who are extremely cold are not getting oxygen to their cells. And yet, they're sometimes alive.

One of my first festivals was Oxygen 2006. It had this amazing lineup with the Arctic Monkeys on their first or second album, the Strokes, Kings of Leon, the Magic Numbers and then the Who and James Brown. I waited in the pit for a good eight hours to see James Brown.

I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.

If your breath is very deep in the lungs, it will give you a good red blood. Good red blood, with the oxygen, is quite sufficiently empowered to take away impurities. When the lungs start clearing the blood, then the liver, spleen, and kidneys have much less work to do.

I remember in 1967, when there was that terrible fire on NASA's Apollo 1 rocket that killed three astronauts, my father made pure oxygen and we lit this tiny cup and burned it. Suddenly, we had an unbelievable jet and a fire. You just could see exactly what had happened.

We may indeed live yet to see, or at least we may feel some confidence that those who come after us will see, such bodies as oxygen and hydrogen in the liquid, perhaps even in the solid state, and the question of their metallic or non-metallic nature thereby finally settled.

Here's the problem, when you're stargazing on a mountain top you are partially oxygen-deprived and you're in command of million dollars worth of hardware. So as much as I would like to sip wine under the stars, it's contraindicated in the instructions on operating telescopes.

Her visits to her former hometown were infrequent and often painful. Pilgrimages fueled by the tepid oxygen of family duty, unease, guilt. The more Esther loved her parents, the more helpless she felt, as they aged, to protect them from harm. A moral coward, she kept her distance.

Trump was always a poster boy of the selfish, egomaniacal, ignorant, bragging, cruel rich kid, whose mirror was the sleazy pages of Rupert Murdoch's 'New York Post.' Trump's oxygen was the leaked item, without which he would die the suffocating death of being shown to a bad table.

When I was 13, I came back from summer camp - summer of '74 - and my mother had had an accident during surgery and was in an oxygen tent in a coma. It was so traumatic. My parents had been divorced for six or seven years at that point, and it was sort of the seminal event of my life.

Even in the investigations into direct production of calcium peroxide in an alkali melt with highly compressed oxygen, it was found to be necessary to bring the high-pressure gas into contact with the suspension of lime in caustic alkali melt by agitation or some other means of mixing.

When there is enough oxygen in the air for everyone, no one is going to take to violence in order to access it. But if there were not enough of it for everyone then people would result to violence in order to get it. Therefore we have to improve the conditions to have better human beings.

A drop of water is not immortal; it can be resolved into oxygen and hydrogen. If, therefore, a drop of water were to maintain that it had a quality of aqueousness which would survive its dissolution we should be inclined to be skeptical. In like manner we know that the brain is not immortal.

Hope is to our spirits what oxygen is to our lungs. Lose hope and you die. They may not bury you for awhile, but without hope you are dead inside. The only way to face the future is to fly straight into it on the wings of hope....hope is the energy of the soul. Hope is the power of tomorrow.

Kamala Harris is fumbling and she's like, 'Oh, I'm going to go after Twitter because Elizabeth Warren sucked all the oxygen out of the room.' She's standing up and saying, 'I'm going to go after Facebook, I'm going to break them up, I'm going to go after all of these big technology companies.'

I hit Damian Fuller with a left hook that left him laid out for 30-45 minutes. They brought oxygen to him, they couldn't wake him up, he was out cold. The television station kept having to take breaks, he was out so long. It was unbelievable. That was the best one-shot I've ever done in my life.

What keeps earth air breathable? Not oxygen alone. The earth is a freer place to breathe in, every time you love without calculating a return -- every time you make your drudgeries and routines still more inefficient by stopping to experience the shock of beauty wherever it unpredictably flickers.

Freedom of speech is, to all Americans, as oxygen is to the human condition. It is a right that has been irreversibly programmed into our hard drive. We are free to speak our minds. An artist's right to express him or herself as best suits their art, is the artist's prerogative and it is guaranteed.

We were looking for the Rick Perries, the Scott Walkers, the Bobby Jindals, all to probably still be on the stage.They`re all gone and [Donald] Trump has sucked the oxygen out of race and made it a national race courtesy a little bit of NBC making him a celebrity, second of all, just his personality.

Think of the actual physical elements that compose our bodies: we are 98 percent hydrogen and oxygen and carbon. That's table sugar. You are made of the same stuff as table sugar. Just a couple of tiny differences here and there and look what happened to the sugar: it can stand upright and send tweets.

You'd think skiing wouldn't be strenuous - all you have to do, after all, is start at the top and let gravity pull you to the dessert bar in the lodge. But at those elevations, you'll find about as much oxygen as you'll find kindness from your children. It's like spending six hours holding your breath.

Of the over 100,000 wildfires that happen in the U.S. each year, not a single one would get started without the fire triangle: Oxygen, heat and fuel. Fire needs all three to exist. It's like the three branches of our government: Legislative, judicial and executive. The fewer there are, the safer we are.

Civil society space provides the oxygen for citizens to participate and meaningfully hold their governments and the private sector to account - and ensure that decisions are made in the interest of the majority and not the few. Without it, citizens have limited space to dissent and challenge the elites.

Each summer, for example, nitrogen and phosphate washing from farmlands in the Mississippi Valley enter the Gulf of Mexico, creating a massive algal bloom covering some 16,000 square kilometers. As the blooms die off, this area-roughly the size of New Jersey-is so deprived of oxygen that no fish survive.

Every revival in history seems to be the result of a few people becoming so hungry for God that they wanted Him more than oxygen. Those who have such hunger will not be denied. It's time to seek a revival that becomes the most famous address in the world. It's time to seek a move of God that won't quit moving.

A new laboratory technique, positron emission tomography, uses radioactively labeled oxygen or glucose that essentially lights up specific and different areas of the brain being activated when a person speaks words or sees words or hears words, revealing the organic location for areas of behavioral malfunction.

There's not as much oxygen in that hot gym and I think it's great for conditioning. I believe in a lot of boxing. You can train and work on the speed bag and heavy bag, but when you get in the ring with another fighter, it's a different story. Punches are coming at you, there's physical contact, muscle against muscle.

I used to fall into the trap of thinking that taking care of my husband and kids was more important than taking care of myself. Now I have a new attitude: You know when you're on an airplane and the manual tells you to put on your oxygen mask first and then help the person next to you? I feel the same way about my health.

Insurgencies are easy to make and hard to stop. Only a few ingredients need to combine to create an insurgency; like oxygen and fire, they're very common and mix all too often. The recipe is, simply, a legitimate grievance against a state, a state that refuses to compromise, a quorum of angry people, and access to weapons.

Waterboarding is slow-motion suffocation with enough time to contemplate the inevitability of blackout and expiration. Usually, the person goes into hysterics on the board. For the uninitiated, it is horrifying to watch. If it goes wrong, it can lead straight to terminal hypoxia - meaning, the loss of all oxygen to the cells.

Here in the United States we're now consuming about three gallons of petroleum per person per day. That's twenty pounds of oil per person per day. We only consume about four pounds of oxygen per person per day. We're consuming five times more oil each day, here in the United States than we are oxygen. We've become the oil tribe.

Sometimes, I tell my wife I have to take a car trip and collect new memories - I like to drive around at absolute random for weeks on end through the United States and parts of Canada. Or else I feel trapped, like you feel when your life is completely planned for months in advance, and you think you're not getting enough oxygen.

The purpose of fear, clearly, is to help you get away - which it does. If your heart rate increases, there is more blood pumping so you can use that blood to fuel your muscles to run away. Oxygen is sent to the lungs so you can run fast. Pupils dilating help you see in the dark. All of that prepares your body to fight or escape.

Never assume that you have attained truth. Don't make any claim to knowledge. Form no conclusion or evaluation concerning truth. The minute you do, your downfall is assured. Whenever you imagine you know something, you cease being open to the living exploration. You have closed a door and cut off the oxygen to the breathing truth.

The clearest evidence that we are living beyond environmental means is the threat of dangerous climate change. The scale of this threat, to human life and to the natural resources and assets on which it depends, for everything from oxygen and clean water to healthy soils and flood defence, means that this simply must be our top priority

You lived and died alone, especially in fighters. Fighters. Somehow, despite everything, that word had not become sterile. You slipped into the hollow cockpit and strapped and plugged yourself into the machine. The canopy ground shut and sealed you off. Your oxygen, your very breath, you carried into the chilled vacuum, in a steel bottle.

I was interested by the idea that artists working in a totalitarian dictatorship or tsarist autocracy are secretly and slightly shamefully envied by artists who work in freedom. They have the gratification of intense interest: the authorities want to put them in jail, while there are younger readers for whom what they write is pure oxygen.

If you ever really want to get away from it all and see something that you have never seen, and have an excellent chance of seeing something no one has ever seen, get in a sub. You climb in, seal the hatch, turn on a little oxygen, turn on the scrubber, which removes the CO2 in the air you breathe, and they chuck you overboard. Down you go.

Russell James asked me to shoot underwater. He tied my feet under the water. I don't know how many feet - maybe five, six meters. He tied me underwater and I had no air. Somebody had a tube, and they were giving me some oxygen, but I couldn't really see anything. Everything was blurry. I'm waiting for the oxygen - that was the craziest thing.

An adult human can last 40 days without food, a week without any sleep, three days without water, but only five minutes without air. Yet nothing is more taken for granted than the air we breathe. However, not just any air will do - it must be exquisitely designed to meet our needs. Too little oxygen in the atmosphere will kill us, as will too much.
