The truth is that even big collections of ordinary books distort space, as can readily be proved by anyone who has been around a really old-fashioned secondhand bookshop, one that looks as though they were designed by M. Escher on a bad day and has more stairways than storeys and those rows of shelves which end in little doors that are surely too small for a full-sized human to enter. The relevant equation is: Knowledge = power = energy = matter = mass; a good bookshop is just a genteel Black Hole that knows how to read.

I think I would like to go into modelling. Of course, I don't know how to do it, and wouldn't be any good at it if I did, so I'm going to employ someone to walk the catwalks on my behalf. It would still be me, of course.

A good banana daiquiri is hard to come by. I've only ever found one place in this country that makes a proper one, and that's in Leeds.
