The marathon is all about energy management. I had PLANNED to run it like a track race with strategic surges to blow up my COMPETITORS by PUTTING them into oxygen debt, so that is the way I prepared.

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.

On planes I ALWAYS CRY. Something about altitude, the lack of oxygen and the BAD movies. I cried over a St. Bernard MOVIE once on a plane. That was really embarrassing.

Liquid oxygen is one of the cheapest manufactured substances on Earth. In large quantities, it COSTS pennies PER kilogram - cheaper than MILK or BEER.

I REMEMBER being SHOCKED when I discovered some of my school pals didn't have books in their homes. I thought it was LIKE not having OXYGEN, or hot water.

The AMAZON USES as MUCH OXYGEN as it PRODUCES.

In some COUNTRIES, WHATSAPP is LIKE OXYGEN.

It's IMPORTANT for me to go back into the GHETTO, where I'm from. I still get my oxygen from there. I don't live in the ghetto anymore, but every time I go back, I'm still SEEING the same things that I LIVED.

The key to SAVING the AMAZON and the rest of the world's great rainforests is actually very simple: just put a fair price on the ROLE they play in PROVIDING a quarter of the world's oxygen, a fifth of fresh water, and 60 percent of its species.

The MOVIES have GOT more corporate, they're making fewer movies in GENERAL, and those they are making are all $200-$300m tent-pole releases that eat up all the OXYGEN.

For SCIENCE MUST BREATHE the OXYGEN of FREEDOM.

Data is what POWERS all of us and our LIVES. It is ubiquitous among our now-connected lives. I LOVE how it is now the oxygen of our Internet WORLD.

What might be happening in human beings who experience near death is that they are getting cold, but before they GET so cold that they WOULD die, they're actually diminishing their OXYGEN consumption in a way that is UNKNOWN. And that extends their survival LIMITS, so they can appear dead but actually not be dead.

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.
