Activating oxygen can produce compounds called radicals that put oxidative stress on cells. Such stress could ultimately lead to cancer and other diseases.
John Simon

All these older kids here, and I'm the only one from a town that's so small, if everyone breathed at the same time, you'd run out of oxygen. Man, there is nothing there.
Herschel Walker

Among the notable things about fire is that it also requires oxygen to burn - exactly like its enemy, life. Thereby are life and flames so often compared.
Otto Weininger

Basic human contact - the meeting of eyes, the exchanging of words - is to the psyche what oxygen is to the brain. If you're feeling abandoned by the world, interact with anyone you can.
Martha Beck

Democratic nations must try to find ways to starve the terrorist and the hijacker of the oxygen of publicity on which they depend.
Margaret Thatcher

Eventually it just got really crazy. Less and less oxygen in the apartment.
Eric San

For science must breathe the oxygen of freedom.
John Charles Polanyi

Freedom is the oxygen of the soul.
Moshe Dayan

Freedom is the oxygen without which science cannot breathe.
David Sarnoff

God is a spirit. A spirit is as much matter as oxygen or hydrogen.
Orson Pratt

He's so ugly he should have to wear an oxygen mask.
Mickey Rivers

Hyperbole was to Lyndon Johnson what oxygen is to life.
Bill Moyers

I explained I wanted to descend as quickly as possible to camp IV in order to warm myself and gather a supply of hot drink and oxygen in the event I might need to go back up the mountain to assist descending climbers.
Anatoli Boukreev

I have no ego investment in being on the air. I don't knock others for whom that kind of attention is like oxygen, but I don't miss anything about it.
Hugh Downs

I said to Scott that the ascent seemed to be going slowly and that I was concerned descending climbers could possibly run out of oxygen before their return to camp IV.
Anatoli Boukreev

I think that people ran out of oxygen and don't really know what happened up there, maybe some of them just made things up because they weren't sure what had happened.
Anatoli Boukreev

In the course of my stay there, I also showed how one could analyse the experimental kinetic curves for the reaction of haemoglobin with carbon dioxide or oxygen by simulations in the computer, and so fit the rate constants.
Aaron Klug

Information is the oxygen of the modern age. It seeps through the walls topped by barbed wire, it wafts across the electrified borders.
Ronald Reagan

Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.
Asa Gray

Money isn't the most important thing in life, but it's reasonably close to oxygen on the "gotta have it" scale.
