This is a book for the elderly and not-so-elderly who are bamboozled not just by the technology of the contemporary world, but also various modern concepts and conceits that the more youthful take for granted. It explains a host of modern concepts and technologies that have entered everyday use and parlance but which are alien (and possibly frightening) not just to the elderly - but probably also to anyone over 45. These concepts are universal and should therefore appeal to readers in the UK, Australia, US and Europe. The definitions are all real, but entertaining, making use of easy-to-understand 'real world' references or examples to explain them.
