have you ever thought about hoe your body works ? Every day you make your body do lots of different actions, such as when you walk, talk, or dance. But at the same time, your body automatically does many othr things that are essential for ever yday life. For instance, when you blink or yawn or breathe, you don't have to think about what you are doing; you body simply carries out these tasks for you. You might think this is strange, but the latest houses are like this, too.
