This book is made up from readers' answers to a broad range of questions posed in the New Scientist magazine. In many cases the questions are more intriguing than the answers (which can get fairly scientific) - one example being: if you were to eat your own body, what would be the LEAST nutritious part?! Because the answers are all written by different individuals, they vary in tone from being highly technical to very amusing. But for the most part the answer to the question "Do scientists have a sense of humour" would most definitely be yes.
It's a great book to flick through with no one answer taking more than a couple of minutes to read. I can think of several men who would consider this the perfect book to have sitting by the toilet. I bought this book for a bright eleven year old who thinks it's brilliant. Entertaining and informative.
And do Polar Bears get lonely? Apparently not. Other polar bears represent competition for food and are invading their territory. Mother bears tolerate their own offspring until they are fully grown, but then they are expected to find their own territory.
