How is the life of astronauts in space different from ours?

Astronauts working in space need a combination of work and rest to complete the heavy space scientific research tasks. In order to kill free time, astronauts created baseball, football, "indoor" golf and water polo games in weightlessness. When they feel bored and lonely, they will tell jokes, anecdotes, create humor and engage in comedies. People who really don't want to move can watch TV, electronic newspapers and famous books, and send "Yi Meier" to friends and relatives on earth.

Astronauts don't have to wear shoes in space, and there are no so-called special shoes.

Astronauts will grow taller in space. Because under the condition of long-term weightlessness, the vertebrae of the human body can generally grow to a height of 2.5 ~ 5 cm because they are not compressed by gravity and expand each other.

Astronauts are always "unaccompanied" in the vast space. In order to alleviate their loneliness in space, scientists have thought of many ways. After the 1980s, the United States and the former Soviet Union successively set up "special telephone lines for space" so that astronauts could talk with their families. Nasa also announced the telephone number 900-4 10-6272, making it a busy hotline for every space shuttle.
