Why do stars twinkle? Why can't we remember names? Why does the Leaning Tower of Pisa lean? Why does hair go grey? Why don't penguins get frozen feet? Why do detergents make white clothes whiter? Why are so many games called football? Brilliantly illustrated, here are hundreds of questions and authoritative answers about space and Earth, how our bodies work, why we observe age-old customs and traditions. There are also revealing insights into Nature's mysteries and the modern marvels of our homes and workplaces. The questions, seemingly simple, open doors to a wealth of interesting information and anecdotes on just about everything under the Sun and beyond; questions you might well have asked and to which nobody could offer you an answer.
