“If your pillow is six years old (apparently 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.”

“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.”

“... it occurred to me that never again would he be seven years, one month and six days old, so we had better catch these moments while we can.”

“The current best estimate for the Earth’s weight is 5.9725 billion trillion tonnes, a difference of only about 1 per cent from Cavendish’s finding.”

“Look at a globe and what you are seeing really is a snapshot of the continents as they have been for just one-tenth of 1 per cent of the earths history.”

Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from its life's quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result -- eventually, astoundingly, and all too briefly -- in you.”
