When you do sport, you often breathe a lot., When you breathe, the air moves in and out of the lungs., Put your hands on your chest and see what happens when you breathe in and breathe out., Breathing fresh air is good for you., Please, hold your breath., Please, breathe slowly., When you run on the spot for one minute you breathe faster., How tall are you?, Measure your height with a tape measure., Take a deep breath., Blow all the air in your lungs into the balloon..
