Living among the stars isn't all about the more formal professional duties, life's basic necessities must be taken care of as well. You don't have to do things like go to the bank or pick the kids up from school, but you do need to shower, clean your clothes, and get a haircut. If you're staying on the International Space Station for a whole year, personal care, fun, and relaxation will be essential ingredients in your quality of life.
