Why do astronauts have to jog at least once a day while in space?

• Astronauts must be in good shape in order to continue going into space, so they have to exercise a lot.

• There isn't enough space in the space station for them to do any other form of exercise.

• They don't have gravity to work against, so they have to jog to trick their bodies into thinking there is gravity.

• They don't have gravity to work against, so they don't get much exercise floating around.

In what ways is living on the space station different than living on Earth?

• Astronauts sleep while floating around, instead of laying on a bed.

• Astronauts shower in a pod and have to scrape water off, instead of in a shower where the water runs off.

• Astronauts have to jog every day, instead of going to a gym or out for walk at the park.

• All of the above

Why do astronauts have a hard time adjusting back to life on Earth after leaving the space station?

• They aren't used to the gravity, so their lungs have to adjust to breathing under the pressure again.

• They aren't used to living among that many people after only being with 3 people for so long.

• They aren't used to the gravity, so their arms and legs feel heavy and off balance.

• They aren't used to normal, daily task of Earth, like showering and sleeping anymore.
