"Victorian rigidities were such that ladies were not even allowed to blow out candles in mixed company, as that required them to pucker their lips suggestively. They could not say that they were going "to bed" — that planted too stimulating an image — but merely that they were "retiring." It became effectively impossible to discuss clothing in even a clinical sense without resort to euphemisms. Trousers became "nether integuments" or simply "inexpressibles" and underwear was "linen." Women could refer among themselves to petticoats or, in hushed tones, stockings, but could mention almost nothing else that brushed bare flesh."

An increase of only a degree or so in body temperature has been shown to slow the replication rate of viruses by a factor of two hundred — an astonishing increase in self-defense from only a very modest rise in warmth.

"Wow, look at all the places you can park,” he said, as if for all these years he had been cruising endlessly, unable to terminate a journey. For about a year the most dangerous place to drive in Des Moines was the parking lot of Merle Hay Mall because of all the cars speeding at joyous random angles across its boundless blacktop without reflecting that other happy souls might be doing likewise.

It wasn't until we dropped him at his university dormitory and left him there looking touchingly lost and bewildered amid an assortment of cardboard boxes and suitcases in a spartan room not unlike a prison cell that it really hit home that he was vanishing out of our lives and into his own.

By the 1920s if you wanted to work behind a lunch counter you needed to know that 'Noah's boy' was a slice of ham (since Ham was one of Noah’s sons) and that 'burn one' or 'grease spot' designated a hamburger. 'He'll take a chance' or 'clean the kitchen' meant an order of hash, 'Adam and Eve on a raft' was two poached eggs on toast, 'cats' eyes' was tapioca pudding, 'bird seed' was cereal, 'whistleberries' were baked beans, and 'dough well done with cow to cover' was the somewhat labored way of calling for an order of toast and butter. Food that had been waiting too long was said to be 'growing a beard'. Many of these shorthand terms have since entered the mainstream, notably BLT for a bacon, lettuce, and tomato sandwich, 'over easy' and 'sunny side up' in respect of eggs, and 'hold' as in 'hold the mayo'.

"The American woods have been unnerving people for 300 years. The inestimably priggish and tiresome Henry David Thoreau thought nature was splendid, splendid indeed, so long as he could stroll to town for cakes and barley wine, but when he experienced real wilderness, on a vist to Katahdin in 1846, he was unnerved to the cored. This wasn't the tame world of overgrown orchards and sun-dappled paths that passed for wilderness in suburban Concord, Massachusetts, but a forbiggind, oppressive, primeval country that was "grim and wild . . .savage and dreary," fit only for "men nearer of kin to the rocks and wild animals than we." The experience left him, in the words of one biographer, "near hysterical.

The Smokies seem to be in the process of losing most of their mussels. The National Park Service actually has something of a tradition of making things extinct. Bryce Canyon National Park is perhaps the most interesting—certainly the most striking—example. It was founded in 1923 and in less than half a century under the Park Service’s stewardship lost seven species of mammal—the white-tailed jackrabbit, prairie dog, pronghorn antelope, flying squirrel, beaver, red fox, and spotted skunk. Quite an achievement when you consider that these animals had survived in Bryce Canyon for tens of millions of years before the Park Service took an interest in them. Altogether, forty-two species of mammal have disappeared from America’s national parks this century.

He hit the water—impacted really is the word for it—at over six hundred miles an hour, with a report so loud that it made birds fly out of trees up to three miles away. At such a speed water effectively becomes a solid. I don’t believe Mr. Milton penetrated it at all, but just bounced off it about fifteen feet, limbs suddenly very loose, and then lay on top of it, still, like an autumn leaf, spinning gently.

So without an original or helpful thought in my head, I just sat for some minutes and watched these poor disconnected people shuffle past. Then I did what most white Australians do. I read my newspaper and drank my coffee and didn't see them anymore.

I know this goes without saying, but Stonehenge really was the most incredible accomplishment. It took five hundred men just to pull each sarsen, plus a hundred more to dash around positioning the rollers. Just think about it for a minute. Can you imagine trying to talk six hundred people into helping you drag a fifty-ton stone eighteen miles across the countryside and muscle it into an upright position, and then saying, 'Right, lads! Another twenty like that, plus some lintels and maybe a couple of dozen nice bluestones from Wales, and we can party!' Whoever was the person behind Stonehenge was one dickens of a motivator, I'll tell you that.

You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 X 10^18 joules of potential energy — enough to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point. Everything has this kind of energy trapped within it. We're just not very good at getting it out. Even a uranium bomb — the most energetic thing we have produced yet — releases less than 1 percent of the energy it could release if only we were more cunning.

But what is life to a lichen? Yet its impulse to exist, to be, is every bit as strong as ours — arguably even stronger. If I were told that I had to spend decades being a furry growth on a rock in the woods, I believe I would lose the will to go on.
