Apparently, like loads of other people, I go around thinking that I still know everything that I learnt at school, when in fact, I bet I can't remember half of it, and it wasn't even that long ago! When someone actually asked me to tell them what photosynthesis was I found that I no longer knew anything more than 'it's how plants live and something to do with carbon dioxide and green stuff in leaves'! And more disturbingly all my basic maths skills have also got lost somewhere in the depths of time. This book is a godsend to anyone who wants to be reminded of all these skills so that you no longer feel like a dunce at the pub quiz or just generally really, and it also has loads of things that I was never even taught at school which are of genuine interest. It looks so nice on your shelf too that its a good one to buy for awkward relatives and friends - as long as they won't be insulted!!
