“I think for the U.S. government the Sandinistas represented a threat to their dominance of Latin America.”

Indeed, if your pillow is six years old–which is apparently about the average age for a pillow–it has been estimated that one-tenth of its weight will be made up of sloughed skin, living mites, dead mites and mite dung.

It is the only sport that shares its name with an insect. It is the only sport in which spectators burn as many calories as players – more if they are moderately restless.

Traveling makes you realize what an immeasurably nice place much of America could be if only people possessed the same instinct for preservation as they do in Europe.

Time, you discover, has wrought changes that leave you feeling mildly foolish and out of touch.

Those who sniff decay in every shift of sense or alteration of usage do the language no service. Too often for such people the notion of good English has less to do with expressing ideas clearly than with making words conform to some arbitrary pattern.

Don’t you believe it. Bacteria may not build cities or have interesting social lives, but they will be here when the Sun explodes. This is their planet, and we are on it only because they allow us to be.

If you believe in god, it’s much more fantastic to believe that he created this universe billions of years ago and set in motion this long train of activities that eventually resulted in us. I think that’s so much more satisfying, more thrilling, than the idea that it was all done in seven days.

Ordnance Survey maps, tea and crumpets, summer showers and foggy winter evenings – every bit of it.

So that buildings and structures you normally pass without a glance suddenly become arresting, even beautiful? Well, they seem to have that light in Australia nearly all the time.

I love everything about motels. I can’t help myself. I still get excited every time I slip a key into a motel room door and fling it open.

When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.

It is a slightly arresting notion that if you were to pick yourself apart with tweezers, one atom at a time, you would produce a mound of fine atomic dust, none of which had ever been alive but all of which had once been you.
