We forget just how painfully dim the world was before electricity. A candle, a good candle, provides barely a hundredth of the illumination of a single 100 watt light bulb.

Your pillow alone may be home to 40 million bed mites. (To them your head is just one large oily bon-bon). And don't think a clean pillow-case will make a difference... 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.

Woods are not like other spaces. To begin with, they are cubic. Their trees surround you, loom over you, press in from all sides. Woods choke off views & leave you muddled & without bearings. They make you feel small & confused & vulnerable, like a small child lost in a crowd of strange legs. Stand in a desert or prairie & you know you are in a big space.

It's hard not to be kind of pessimistic about human beings generally, because we do tend to mess things up. If you just look at the history of extinctions, we've killed off an awful lot of animals - and I don't think we're doing a very good job of looking after the planet.

English grammar is so complex and confusing for the one very simple reason that its rules and terminology are based on Latin - a language with which it has precious little in common.

No one knows, incidentally, why Australia's spiders are so extravagantly toxic; capturing small insects and injecting them with enough poison to drop a horse would appear to be the most literal case of overkill. Still, it does mean that everyone gives them lots of space.

The great failure in education, much of the time, is the lack of excitement and stimulus
