Living in the International Space Station (ISS). Everything in the ISS floats so it is difficult to sleep, change clothed and eat. Therefore there are fasteners which help. After the astronauts wake up, they can shower, eat,exercise and work. The food is mostly froze , dehydrated, or heat stabilized. In space the astronauts do not use their muscles a lot so the muscles become weaker. This is why exercise is needed to keep the muscles working. When an astronaut becomes injured, the medical officer will be the one to treat a patient. Each astronaut has different roles. The astronauts keep themselves busy by bringing their own entertainment such as music and books. They can also look out the window to see the beautiful view. In the ISS, the temperature is kept stable therefore they can wear anything comfortable.
