Dear Jim,
I'm writing to introduce to you how the astronauts stay healthy in space.
Living in space is not the same as living on Earth. In space, astronauts float. They do not use their legs much and their lower backs begin to lose strength, causing the bones to get weak and thin, which is very bad for astronauts' bodies.
The heart and blood change in space, too. In space, without the pull of gravity, the blood moves to the upper body and head. When the astronauts come back to Earth, the astronauts have to rest so their bodies have time to make new blood and water. If they don't, they can feel very weak. They might even faint!
Hoping you can have a knowledge of the life in space.
Yours,
