An astronaut's work may sound exciting, but living in space isn't as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them. When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts' fingernails  and even make them fall off. In space, you don't have many choices in what you eat. It's hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs . Crumbs could fly around everywhere. In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting  gun and a washcloth. Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they're in space to try to keep their bones strong as long as possible. Perhaps the hardest part of life in space is the feeling of loneliness. Astronauts sometimes have to spend weeks and even months away from Earth. They miss their friends and families. How do the astronauts keep their bones strong in space?
By taking medicine. By doing exercise. By taking a good rest. By walking in space.
