For answers to all these questions, and so many more, then do yourself a favour and pick up the latest collection from the New Scientist's [http://www.last-word.com/ Last Word column]. Everything is as great as it has been in previous years, with no sign of getting stale or unoriginal. Highly recommended.  Mick O'Hare was also kind enough to be [[The Interview: Bookbag Talks To Mick O'Hare|interviewed by Bookbag]].
