You want to shock the body and not be constant. Intermittent fasting is an increasingly popular way: Skip breakfast, for example. Also lifting weights, losing your breath from exercise and alternating between hot and cold temperatures. We think these measures will only get us to 100 to 122 years old. That's our natural lifespan.

Copper is a superb cooking metal, conducting heat so evenly it has unparalleled control, especially at low temperatures.

Andrew Zimmern

There is no doubt that we should take solar radiation into account. We have seen ground temperatures rising since 1975, and it is important to know to what extent that has been caused by the sun or by carbon dioxide.

Bjorn Lomborg

The best scientific evidence suggests temperatures are rising, and the best scientific evidence suggests man-made anthropogenic carbon emissions have some substantial thing to do with that. However, does that mean the trend will continue forever? We don't know.

Bret Stephens

On our way to the Super Bowl XV Championship, the Oakland Raiders played a frigid 1981 AFC playoff game in Cleveland, in which the temperatures plunged to -35 degrees. I remember looking up in the stands to see a dedicated Cleveland Brown fan celebrating topless.

Titan has no liquid water on its surface, and any liquid water beneath its surface is inaccessible to us, as far as we know. It has hydrocarbon lakes, but we don't know of any organisms that could live in those, not at the temperatures that we find on Titan. Any reference to possible life in lakes on the surface of Titan is pure speculation.

Carolyn Porco

We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.

Cary Fowler

Climate change is the greatest threat to humanity, perhaps ever. Global temperatures are rising at an unprecedented rate, causing drought and forest fires and impacting human health.

Cary Kennedy

In recent years, our planet has been warming at an alarming rate and seen record-breaking temperatures. We are now witnessing the sixth mass extinction event in the earth's geologic history. Our sea levels are rising at an alarming rate, threatening our largest cities, like New York, Los Angeles, and Miami.

Catherine Cortez-Masto

It was remarkable to see from space how predictable people are. Our homes and towns are almost all in places with moderate temperatures, and they generally have the same shape - a thinly occupied outer blob of suburb surrounding a densely populated core, all based around a ready source of water.

Chris Hadfield

Sometimes I think about all the hours spent making lunches, carting kids from one place to another, being up in the middle of the night taking temperatures. People who haven't had to do that have, say, read every last book up there from cover to cover and probably remember it. There are trade-offs. But more life is more life.

When very large stars die, they create temperatures so high that protons begin to fuse in all sorts of exotic combinations, to form all the elements of the periodic table. If, like me, you're wearing a gold ring, it was forged in a supernova explosion.

David Christian

As Earth's climate changes, we can expect more destructive hurricanes. As sea level and surface temperatures rise, more solar energy is trapped in the atmosphere, revving up the hydrological cycle of evaporation and precipitation and sometimes manifesting in terrifying storms.

David Grinspoon

Prominent scientists have become increasingly convinced that the connection between carbon emissions and rising temperatures is real, but skeptics have whole truckloads of studies to demonstrate the opposite.

David Ignatius

The primitive fight-or-flight regions of our mammalian brains react to immediate danger. We instinctively run from an avalanche but the gradual retreat of a glacier, the portent of the far greater danger of rising temperatures and rising oceans, just doesn't get through to us in the same way.

David Olusoga

And I've shot in Prince Edward Island winters, I mean, I've shot in some intense, intense temperatures.

Ellen Page

A colour is a physical object as soon as we consider its dependence, for instance, upon its luminous source, upon other colours, upon temperatures, upon spaces, and so forth.

Ernst Mach

Sleephackers go to bed with sensors on their wrists and foreheads and maintain detailed electronic sleep diaries, which they often share online. To shift between sleep phases, sleephackers experiment with various diets, room and body temperatures, and kinds of pre-sleep physical exercise.

Evgeny Morozov

The science tells us that if we fail to reduce global warming pollution, global temperatures will rise to dangerous levels and unleash devastating extreme weather events and accelerate destructive sea level rise.

Frances Beinecke

Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.
