   This book tell us about many kind of invention, I like the story of toilets. Long ago, people were squatting behind a tree. The ancient Romans had public toilets and the toilets were long and stone slab with holes over a deep trench. And then, going to the toilets became a great way to meet people. But after that people were shy to meet other people in the toilets. So they made a private room in the toilets. Toilets have evolved for a long time and I think they are going to evolve in the future.
