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