No one said it was easy to adjust to life on Earth after living in space.
And according to a newly released video from NASA astronaut Drew Feustel, one of those symptoms is being unable to walk a straight line with your eyes closed.
Feustel posted the video to Twitter after some of his colleagues came home from the space station on Thursday.
Welcome home #SoyuzMS09 ! On October 5th this is what I looked like walking heel-toe eyes closed after 197 days on @Space_Station during the Field Test experiment…I hope the newly returned crew feels a lot better. Video credit @IndiraFeustel pic.twitter.com/KsFuJgoYXh

Feustel spent close to 200 days floating in the weightlessness of the space station, so it’s understandable that he might have a little trouble walking heel to toe once back on Earth.
Astronauts exercise for about two hours every day when in space to keep up muscle mass and bone density while in microgravity, but that doesn’t mean that it’s automatically simple to walk upright in Earth’s gravity.
Once back on Earth, astronauts and cosmonauts have to go through a series of physical and medical tests to see how their bodies withstood living in space.
If we want to send humans to Mars one day, scientists need to understand exactly how the human body reacts to long-duration spaceflight from weightlessness to radiation exposure.
Long missions to the space station — like astronaut Scott Kelly’s year spent aboard the orbiting laboratory — will be key to understanding exactly what medical issues may crop up during trips to far-flung places in deep space.
